INTRODUCTIONConcrete is essentially a very simple matrix. It is generallycomposed of three basic ingredients: aggregates, cement and water.Cement and water form a paste, cementing large and fine aggregatesinto a mass' called concrete (Figure 1). Steel reinforcement isadded in desired locations within the concrete mass, so that theycomplement each other.

Cement paste

Figure 1 Concrete matrix

Concrete responds to heat, load and the environment. Itcan shrink, creep, crack and deteriorate. Together with steelreinforcement it acts and responds differently. Concrete takescompression well, leaving tension for the steel to handle. Concretestructures take different forms and have various functions. They canbe artistic as well as functional, depending on how designers shapethem. Concrete can also be ugly (Figure 2) or beautiful (Figure 3).

Although concrete has been around for thousands of years thesearch for new, advanced and sustainable constituent materialsfor concrete is still intensive. Modern days practices and use ofconcrete have changed. While the basic contituents remain thesame, the search (and research) for new or enhanced properties

continues. The need for innovative solutions can be seen from manydifferent aspects. Apart from the need to satisfy new designs andfunctions for concrete structures, the energy crisis, labour issuesand environmental considerations are some of the most dominantfactors that push for continuous innovation in concrete technologyand practices.

The researcher has been involved in a wide range of concreterelated research and development projects. This paper will howeveronly focus on two main areas of his research i.e. the industrializedbuilding system (IBS) and cement replacement. His other workrelated to concrete deterioration and assessment, structuralstrengthening, integral bridges, roller compacted concrete andconstructability can be found in various publications includingJaafar et al (2003), Sutan & Jaafar (2003), Thanoon et al (2005),Abdulkadir et al (2005), Khan et al (2007), Hassim et al (2008),Noorzaei et al (2009), Baghayoob et al (2010), Huda et al (2010)and Ohu et al (2012).

The need to find an innovative structural system to satisfy theIBS requirements is mainly to address the issue of insufficientlocal labour and to transform the practice from conventional to

modern construction practices. This gives rise to the concept ofconstructability and the industrialised building system which callsfor innovative concrete products or systems. The industrialisedbuilding system takes a page from car manufacturing and assembly,where systems are designed and components are prefabricated andassembled with minimal labour force required. Can the buildingindustry face up to this challenge? This inaugural lecture describesthe researcher's role in addressing this need and meeting thischallenge.

Concrete uses natural materials which are not infinite. Asfunctions change, demand for better concrete performance alsochanges. Hence, there is a need to find suitable alternatives toreplace the traditional material or to enhance its properties. Use ofwastes, other naturally occurring materials, additives or differentprocesses has paved the way for many possibilities. Research onvarious forms of concrete materials is discussed in this inaugurallecture.

INDUSTRIALISED BUILDING SYSTEMSThe concrete construction industry has several unwelcomereputa!ions. They may be summed up, as the Construction IndustryDevelopment Board (CIDB) once classified it, as 'Difficult', 'Dirty'and 'Dangerous'. There is thus a clear need to improve the image ofthe concrete construction practice, as exemplified, again, by that ofthe car manufacturing industry. In the car manufacturing industry,a car is designed as an integrated system, but its components can beprefabricated at places other than the assembly location. This posesa big challenge for the building construction industry where thepractice needs to change from conventional construction practicesto that of an industrialised system. The 'industrialisation' of the

1114

Mohd. Saleh Jaafar

building system has become amain stream agenda for stakeholdersin the concrete construction industry.

IBS can mean different things to different people. However,it is accepted that IBS encompasses simple components to fullsystems. Junid (1986) mentioned that an IBS in the constructionindustry includes the industrialised process by which componentsof a building are conceived, planned, designed, fabricated and thentransported and erected on site. The system includes a balancedcombination between the software and hardware components. Thesoftware components include system design, which is a complexprocess of studying the requirements of. the end user, marketanalysis, development of standardised components, establishmentof manufacturing and assembly layout and process, allocation ofresources and materials and definition of a building designer'sconceptual framework. The software elements provide an avenueto create a co~ducive environment for the industrialised buildingsystem to expand.

The hardware components are categorised into three majorgroups. These include the frame or post and beam system, panelsystem and box system. The framed structure is defined as thatstructure which carries the loads through the beams and girdersto the columns and to the ground, whereas in the panel system,loads are distributed through large floor and wall panels. The boxsystems include those systems that employ three-dimensionalmodules (or boxes) for fabrication of habitable units that arecapable of withstanding load from various directions due to theirinternal stability.A subset ofthis is the supply of individual buildingcomponents delivered to site and assembled to fit into a standardmodular design.

The Housing Research Centre (HRC) in UPM has taken theinitiative to develop several innovative solutions to address the needfor the ms. For example, residential housing is the sector withthe greatest need for a quick solution. HRC has thus dedicatedresources to work on systems that address the local conditions andneeds, with the use oflocally available materials and constructionworkers in the country (Kadir, M.R.A et al,,2006).

Towards this end, the development of interlocking hollow blocksand floor slab systems is the main contribution of this researcher.

/:

Interlocking Hollow BlocksInterlocking hollow blocks are considered to be one of the bestoptions to address the need for industrialised building systems inthe country, especially for low-rise residential buildings. The useof interlocking load-bearing hollow blocks in building constructionspeeds up the construction process due to the elimination of theneed for mortar layers. In Malaysia, the supply of houses by boththe public and private sectors is still far from meeting the demand,especially in the affordable housing sector.

The proposed system, using interlocking hollow blocks (IHB),may be the solution to overcome this shortage as these blocks can beused in the construction of both non-load-bearing and load-bearingwalls. The interconnections between the blocks have to be designedto withstand the stresses from different directions at various levels,which develop in a wall under applied loads. In the developmentof the new interlocking block system, the following features havebeen identified as the main desirable characteristics:

• efficient interlocking mechanism in different directions towithstand the different forces (shear and bearing), whichdevelop under applied loads;

1116

Mohd. Saleh laafar

• self-alignment to ensure accurate and simple construction;

meeting modular coordination requirements;

construction of both load-bearing and non-load-bearing walls;and

production norms similar to that of normal hollow blocks sothat the manufacturing machinery is easily fabricated.

Most existing systems using interlocking blocks have beenstudied. Each system has its own strengths and addresses somerequirements of the industrialised building system, but none haveoverall features that are in line with the characteristics required.The research team in UPM has designed and tested 20 differentsystems (see Figure 4) and finally came up with one system thataddresses the overall needs of an industrialised building system.The system, which has been named the 'Putra Block', has beenpatented in Malaysia, USA and the United Kingdom (Figure 5).

Details of the development, performance and application of. this system for housing constructions are available in variouspublications, including those published by Jaafar M.S. et aI, (2006),Thanoon W.A et al. (2004, 2007 and 2008) and Shafiee A.N et al.(2011). A brief summary of the system is reproduced here.

The structural properties of individual blocks, prisms and wallsystems have been thoroughly investigated and properly selected tosatisfy various loading conditions. The system has also been testedand satisfied the requirements for fire resistance. These interlockingmechanisms are designed in such a way that the system can behaveas if the blocks have been placed using conventional mortar layers.

Stress distributions for individual and prism blocks are shownin Figure 6. The maximum compressive stresses are found nearthe applied load while the maximum tensile stresses are locatedat the top corners of the block webs where the webs support the

7111

Advancing Concrete Materials and Systems: The Search Continues

side shell of the blocks. From these figures, it can be observedthat the stress has a maximum value (compression) located at theintersections between the webs and the shells at the bottom edge ofthe top stretcher block. This is a result of connecting two differentgeometric configurations of blocks, i.e. the stretcher and the halfblocks, as well as due to the connecting of different element sizes.The tension zones are confined to the top of the webs in a waysimilar to that in a block unit. The stresses at the top of the webs ofthe stretcher and half blocks are found to be in tension due to the

(

interaction between the shells and the web (action and reaction).

The block dimensions mentioned are in conformity with themodular design rules, which require the horizontal controllingplanes to be in modular dimensions of 3M or 300 mm, and thevertical controlling planes to be 1m or 100 mm. The Half Blockwith 150 mm length can be conveniently put in the technical zonesof 150 mm. This allows other spaces in the house to have modulardimensions, thus facilitating the use of other modularly coordinatedcomponents such as windows, doors and built-in cabinets. It canalso be seen that if the typical room heights of 2800 mm or 3000mm are adopted, there is not a single block that needs to be brokento fit into the spaces required. There will be no wastage of materials,and indeed, the exact number of blocks required for a specific housecan be estimated from the architectural drawing.

Walls can also be constructed using minimal unskilled labour.In addition, the assembled blocks in the wall provide continuoushollow voids, which can be used to host stabilising ties in verticaland horizontal directions to enhance the stability and integrity ofthe system. At the corners or junctions of walls, the connectivitybetween layers is achieved at subsequent layers, as shown in Figure7. This interlocking hollow block system, has been employedefficiently to construct a single-storey house, as shown in Figure8. Reasonable weight and simple shape of the blocks render thesystem friendlier to the workers.

Various experiments have been carried out to determine thematerial properties and structural performance of the blocks. Theexperiments included:

• Individual Blocks;

• Prisms;

• Basic (Standard) Panels;

• Comparison between cube, individual block, prism and basicwall panel;

11111

Advancing Concrete Materials and Systems: The Search Continues

• Failure mechanism;

• Effect of slenderness on wall behaviour;

• Effect of eccentricity on wall behaviour;

• Crack pattern and failure mode; and

• Fire resistance.

The innovative tests set up for the interlocking mechanism, shear-load slip mechanism and individual block stress-strain propertiesare shown in Figures 9 -11. Test results have shown the efficacy of~~ ..._the interlocking mechanisms to avoid the need for mortar layers.This leads to ease of wall construction. The system also performswell under different loading conditions and fire.

Simplified design procedures have also been developed usingthe system and examples for different wall slenderness ratios underdifferent eccentricities are shown in Table 1.

The following conclusions are made based on the extensivetheoretical and experimental investigations that were carried out:

a. The interlocking mechanism is capable of replacing the mortarlayers traditionally used in masonry wall construction. Itplays

,_a significant role in the distribution of stresses that develop inthe block due to the applied load;

b. The theoretical and experimental investigations indicate thatthe system may be used for the construction of load-bearingmasonry walls for single and double-storey residentialbuildings;

c. Design formulae have been developed for the design of load-bearing walls having different slenderness ratios and subjectedto different load eccentricities;

d. A single-storey prototype house has been designed andconstructed at UPM indicating that the system can be usedefficiently.

Precast Slab SystemFloor systems complement the development of interlocking hollowblock systems and form part of the requirement for a completeindustrialised building system. A slab structure occupies the biggestpercentage oftotal dead load and volume for an ordinary residentialstructure. A simple load calculation for a residential building showsthat approximately 40 - 60% of dead load is the self-weight ofthe slab structure [Yavuz Y., 2008]. Thus, approximately 10% ofself-weight reduction from floor slabs may lead to five percent ofself-weight reduction for the entire building. Moreover, it directlyfaces the live load and transfers the load to the beams and columns.

The traditional solid precast slab is found to be challenging forlarge scale projects because of its heavy self-weight, which leadsto dependency on heavier equipment, transportation difficultiesand expensive connections andjoints soluti~ms. In addition, heavy

11116

Mohd. Saleh Jaafar

precast slabs need extra temporary supports during constructionand larger beam and column size, which result in the escalation ofthe overall cost [Kim S. Elliott, 2002].

More than 15 different types of precast slabs have been usedsuccessfully in the construction industry. Five general criteria haveto be considered for the capacity of flooring units: bearing capacity,shear capacity, flexural capacity, deflection limits and handlingrestriction [Kim S. Elliott, 2002]. There is no system which fulfillsall of the above mentioned criteria.

In terms of better structural performance and lower cost,the development of varieties of light weight slabs has become acrucial need. The use of semi-precast panels is increasing rapidlydue to its versatility in transportation, handling and effective jointpractice. In the recent past, a large number of semi-precast panelshave been developed using either ferrocement or composite coldsteel deck with different types of toping concrete [TasomorodionI., 1983; Kaushik SK et al., 1991; Hago A.w., 2005; Ahmed E.

.. & W. Badrozaman, 2002]. Insulating and light weight core panelswere then developed, which greatly increased the desirability ofthis type of construction material. The panel consists of two thinskins of high strength layers and elastic moduli separated by a corethick layer of normally much weaker and lower material density[Salmon C.D. & Amin E., 1997; Salmon C.D. et al., 1997; AminE et al., 1994;].

Composite slab systems have been found to be structurallyeffective with a thin layer of precast member taking into account thebenefits which include: shorter construction time, less dependenceon heavy equipment at job sites, less material wastage, high qualitysmooth surface finish, in situ structural concrete topping and in-fillforming monolithic structures, elimination or great reduction in theneed for props and elimination of conventional formworks [Algirdas

K. et al., 2007; Kubaisy M.A. & Zamin J, 2000; Kubaisy M.A. &Zamin J, 2001; Lee S.L. et al, 1990; A.E. Naaman, 2000].

Thinner precast structure of the composite slab can be achievedwith Ferrocement technology. Ferrocement has been observed toprovide considerable reduction in cracks and their spacing (64 -84%). Additionally, it enhances the ductility and energy absorptionproperties [Yavuz Y., 2008]. Ferrocement is not only an extensionof reinforced concrete but is now also considered a member of thefamily of laminated composites. It can be reinforced with steelor non-metallic meshes such as fiber reinforced polymeric (FRP)meshes [Kubaisy M.A. & Zamin J, 2001]. The addition of fibers ormicro-fibers as secondary reinforcement in the cement matrix, toimprove performance, makes Ferrocement a hybrid composite. Asummary of the weight and size ofthe existing precast slab systemis presented in Table 2.

Precast and cast in situ layers of existing systems are connectedwith 2D or 3D shear trusses. The shear trusses are used as a handlinglocation during transportation and construction. However, thisconnection system has been questioned by many researchers fortheir capacity to carry horizontal load without any separation andhorizontal cracks (Sittichai, 2003;Alfred, 2001; Engstrom, 1982).Moreover, the ability of the shear trusses to be shear connectorsfor two layer composites is yet to be explored.

This study introduces a semi-precast floor slab system,the Ferrocement-AAC composite slab, to address some of theabovementioned shortcomings in existing systems. The new systemconsists of a bottom Ferrocement skin, AAC masonry and in situmortar ribs (Figure 13). The Ferrocement layer is the precast partof the composite slab, which consists of a wire mesh and steelreinforcement, required to resist tensile stresses. The thicknessand reinforcement of this layer will dependI?ainly o~·the span of

the slab. The AAC layer and the in situ ribs provide the necessaryresistance to the compressive forces developed due to bending. Thetwo layers are interconnected using interlocking and rough surfacebetween the precast and cast in situ layers.

The main advantage of this system, amongst others, is itsrelatively lighter weight compared to R.C which will reduce the loadtransferred to the beams or walls. The masonry AAC acts as light,effective insulation ~aterial and at the same time partially resiststhe compression forces developed due to bending of the composite.On site, the construction of the composite slab does not requireheavy equipment to handle the Ferrocement layer. Furthermore, theconstruction does not need any formwork since the bottom layer of

Ferrocement is a precast unit that can be easily fixed in position,using a simple crane, to provide a platform that acts as a formworkfor the brick layer and the in situ concrete ribs. This experimentalstudy is limited to the investigation of the structural performanceof the one way Ferrocement-AAC composite slab subjected totwo-lines loading. The study highlights the effects of the AAClayout on its overall structural response in terms ofload-deflectioncharacteristic, ductility, strain distribution, composite action andfailure load. The test set-ups for flexure and shear are shown inFigure~ 13 and 14, respectively. Figure 15 shows a'Sunple test setup to demonstrate the system's strength.

The proposed composite slab can be used as a structural floorfor residential buildings. The dead load of the slab can be reducedby 23-32% by using the proposed composite slab compared to thesolid RC. The number of longitudinal ribs has a significant effecton the ductility as the specimens with four longitudinal ribs show60% and 28.4% increase in ductility compared to the slab specimenswith two and three longitudinal ribs respectively. Based on strainmonitoring the slabs performed in a fully composite manner untilthe ultimate load. There were no horizontal cracks observed betweenthe two layers of the composite slabs at any stage of loading. Allthe slab specimens show ductile behaviour. Ductility and maximumdeflection of the slabs are good enough to give ample warning beforefailure.

Details of the development and performance of the proposedsystem are available in Thanoon A.M.T. et al. (2008, 2010, and2011), Yardim Y. (2008) and Yardim Y. et al. (2013).

CONCRETE CONSTITUENT MATERIALSThe demand to improve the properties of concrete arises due to theconcurrent development of other materials as well as new areas ofapplication. Normal reinforced concrete structures use concretegrades of around 30MPa. However, when steel industries managedto increase the steel grade from around 400MPa to 1800MPa, theera of prestressed concrete emerged. In order to utilize the highergrade steel, concrete grades need to be increased to around 50MPa.The demand for higher grade concrete continues as the demand forhigher concrete buildings increases. Concrete grade of 80MPa isbecoming more commonly used now for high-rise buildings andlong-span structures.

Compressive strength is not the only property that matters forconcrete structures. Durability and higher tensile strength havebecome important characteristics that are sought after by engineers.Special concrete that suits special requirements is steadily replacingconventional concrete for special structures. Thus, research effortsby this researcher have focused on finding suitable materials andprocesses to enhance the properties of concrete. The main areasof interest include the search for cement replacements and specialconcrete.

CementCement is the most important ingredient that determines the qualityof concrete. Its content has significant implications on the strengthand durability characteristics of concrete.

The manufacturing of Portland cement consists of grinding ofcalcareous materials (limestone or chalk) and argillaceous materials(clay or shale) in certain proportions and mixing and burningthem in a kiln at temperatures of about 1450 "C to form clinker.The clinker is cooled and ground to powder fineness with three to

five percent of gypsum added. There are two processes for cementproduction, which are the wet process and dry process, but, thereare no significant differences in the final products. The dry processis however more economical than the wet process.

The raw materials used for the production of Portland cementconsist mainly of lime, silica, alumina and iron oxide. Duringthe heating stage, these oxides interact with one another to formcomplex compounds, namely, tricalcium silicate (C3S), dicalciumsilicate (C2S), tricalcium aluminate (C3A) and tetr~calciumaluminoferrite (C3AF). Portland cement consists of four maincomponents, which are, tricalcium silicate (C3S), dicalcium silicate(C

2S), tricalcium aluminate (C

3A) and tetracalcium aluminoferrite

(ClA). When the cement comes into contact with water severalchemical reactions occur with its components.

The first two components, C3S and C2S (i.e. 75% of the dryPortland cement) are the main cementitious components in thePortland cement. The products of calcium silicate hydration arenon-crystalline calcium silicate hydrate (C-S-H gel), which isresponsible for the strength and calcium hydroxide (CH), whichremains active for additional reactions. Two main reactions thatare the subject of ongoing search for better concrete properties are:

C3S+5.3H -+CI1SH4 +l.3CH

C2S+4.3H -+C17SH. +O.3CH

(1)

(2)

More CSH gels means better strength. Less CH means moredurable concrete. The search for better concrete properties is focuson finding ways and means to increase CSH and reduce CH content.From the equations, it is clear that in order for the CH to furtherreact and form CSH, silica must be added. However, the challengeremains that not all silica will react under ambient condition to formCSH.

Cement Replacement

The worldwide production of cement accounts for almost 7% of thetotal world CO2 production, and from the projections made by thecement companies, this proportion is expected to remain steady infuture decades. The net world cement production was estimated tobe about two billion tons in year 2010 [Malhotra, V. (2000].

Portland cement is a high energy and resource consumerproduct. Therefore, to conserve resources and save energy, manyattempts are being made to find substitute materials for partialreplacement of cement. Fly ash (FA), silica fume (SF); groundgranulated blast furnace slag (GGBS), metakaolin (MK), rice huskash (RHA) and sugar cane (SC) are some of the most commonsupplementary cementitious materials used in the concrete industry.

A pozzolan may be used with lime or with Portland cement tomake mortars and concrete. In the case of the latter, the pozzolanreacts with the calcium hydroxide (CH) produced from the hydrationof the Portland cement. This reaction produces denser concrete anddevelops secondary cementitious properties due to the pozzolanicreaction.

Many efforts have been made to review the usage ofpozzolanmaterials as partial cement replacement. V.M. Malhotra [Malhotra,v., 1993] presented the use of silica fume, fly ash, rice husk ashand slag in concrete production while industrial slag in highperformance concrete was reviewed by C. Shi and 1. Qian [200]and S. Chandrasekhar et al., [2003] reviewed rice husk ash as thesource of reactive silicaMeanwhile, metakaolin and calcined claywere covered by B.B. Sabir et al. [2001] and R. Siddique and 1.Klaus [2009].

Pozzolan materials may be divided into natural and artificialpozzolan materials. The natural pozzolan materials include allpozzolan derived from volcanic rock, diatomaceous earth and

koalin. Natural pozzolan materials mayor may not require furthertreatment. The second group comprises by-products of pozzolanmaterials where they can be obtained as industrial by-products suchas silica fume, fiy ash, ground granulated blast furnace slag or fromagricultural wastes such as sugar cane and rice husk. By-productmaterials also mayor may not require further processing to be usedas cement replacement materials [Mehta, P. K., & Monteiro, P. 1.M.,2006].

According to their pozzolanic and/or cementitious activity,f.

pozzolan materials can be classified into four categories. Firstly,materials possessing cementitious properties such as GGBS;the second category is high-calcium fiy ash, which possessescementitious and pozzolanic properties, while the third categorypossesses high pozzolanic reactivity, which can be found in silicafume, rice husk ash and metakaolin. Low-calcium fiy ash andother natural materials possessing normal pozzolanic propertiesare classified in the last category [Mehta, P. K., & Monteiro, P. 1.M.2006].

Papadakis et al. [2006] found that pozzolan materials requireCH in order to produce strong products, whereas a cementitiousmaterial itself contains quantities of CaO and can present self-cementitious activity. The quality and quantity of active pozzolandependmainly on twoparameters, the amount oflime that combineswith the pozzolan and the rate at which such a combination occurs[Hewlett, P. C., 2004]. The amount of combined lime dependson the nature of the active phases, their content in the pozzolan,their Si0

2content, the lime/pozzolan mix ratio and the length of

the curing period. Further, the factors associated with the rate ofcombination are specific surface area of the pozzolan, water/solidratio and hydration temperature.

The existing pozzolans are becoming more expensive thanthe Portland cement itself; hence there is a need to find alternativematerials as partial cement replacement. Silica powder or microsilica is found in abundance in some countries. It comes in theform of dune sands (DS) or white sands (WS) (Figure 17). Thesenaturally occurring materials are rich in silica content and havehuge potential. They have thus been the subject of interest in thissector.

Figure 16 Natural and processed dune sand

A summary of existing pozzolans had been presented at theWorld Engineering Congress by Alawad OA et al. (2010). Thescanning electron micrographs of different pozzolan materials,together with dune sands are shown in Figures 18 and 19.

Extensive study has been conducted on dune sand, from itscharacterization to its treatment and effects on concrete properties.The research work is identifying:

• suitable activation methods - chemical, mechanical or heattreatment;

• suitable curing methods - moist curing, low pressure steammethod or high pressure steam method;

27111

Advancing Concrete Materials and Systems: The Search Continues

• effects of different activation and curing methods throughvariousphysical and chemical tests including strength,chemicalattack, shrinkage and permeability test; and

• effects of different activation and curing methods throughmicrostructure examination techniques including Scanningelectron microstructure (SEM), X-ray diffraction (XRD),Thermo-gravimetric (TG) analysis, and Diffraction thermalanalysis (DTA).

The studies also include identification of ternary elementswhere micro silica can be used to the maximum, while reducingPortland cement to the minimum. Some of the results have beenreported in various journal publications (Jaafar M.S. et al., 2002;Alhozaimy A. et al., 2012, 2013).

Important findings obtained from these studies include:

• the possibility of using DS and WS as 30% partial cementreplacement under autoc1aved curing. The temperature andpressures allow for pozzolonic activity to take place for thedune and white sands, as shown by the strength test results andthe microstructural analyses;

• with autoclave curing, all of the binary and ternary mixturesyielded mortar with a compressive strength higher than that ofthe control sample. The autoclave-cured ternary combinationof 30% GDS, 50% PC and 20% GGBS showed the highestcompressive strength;

• the possibility of using a PC content as low as 10% since themixture of 30% GDS, 10% PC and 60% GGBS displayedstrength comparable to the control sample;

11128

Mohd. Saleh Jaafar

the possibility of reducing the PC content by up to 90% byincorporating GDS and GGBS in autoclave-cured mortarmixtures.

These findi~gs have significant implications for the sustainabilityand economy of concrete construction in countries with abundantsupplies of natural dune sands.

Blended Cement

Concrete containing blended cement has experienced rapid growthin the construction industry. It has the potential to save energyas the naturally occurring materials are less energy intensive.Therefore, many attempts are being made to find substitute materialsthat can be used as a partial replacement for PC. Supplementarycementitious materials (SCMs) such as fly ash (FA), silica fume(SF), ground granulated blast furnace slag (GGBS), metakaolin(MK) and rice husk ash (RHA) are some of the most common PCreplacement materials currently used in the concrete industry. Theincorporation of these materials provides many benefits includingtechnical, economic and environmental benefits. The technicalbenefits include the enhancement of fresh concrete properties andfinished concrete with increased ultimate compressive strength andimproved impermeability and durability.

The SCMs are alumino-silicate materials that react withcalcium hydroxide (CH) at ambient temperature in the presence ofmoisture to form the cementitious calcium silicate hydrate (CSH).This action will result in the reduction or removal of CH from theconcrete composite, hence, it has a positive effect on the durabilityand transition zone between cement paste and aggregate. Apartfrom their chemical effects, SCMs help to fill the capillary poresbetween cement grains and thus improve the density of the cementpaste.

GGBS, unlike other SCMs, consists of chemical oxides similarto those in PC but in different proportions. Many studies have beenconducted on the use ofGGBS as an SCM and it has been reportedthat GGBS-supplemented concrete shows a lower early strengthgain compared with plain concrete. Therefore, GGBS is not used inapplications where high early strength is required. However, whenGGBS is added in combination with PC, the hydration of GGBS

31111

Advancing Concrete Materials and Systems: The Search Continues

is accelerated due to the presence of CH and the sulfate compoundgypsum in the PC. It has also been reported that the reactivity ofGGBS is improved at elevated temperatures as inthe case of thermalcuring, which is largely used in the precast concrete industry. Withthe advantage ofGGBS and coupled with the potential of dune sandto be used as cement replacement, a study where these materialsare blended was proposed.

The study (Alawad, O.A. et al., 2014 and Alhozaimy, A. etal., 2013) was to investigate the effect of using ground dune sand

(GDS) as a cement replacement material in binary and ternarycombinations with PC and GGBS on the fresh properties andcompressive strength of mortar. The successful use of GDS toreduce cement consumption can have a potentially significantimpact on the sustainability and economy of concrete construction,especially in countries with unlimited supply of natural dune sands.The findings of this study may be beneficial for the wider applicationof dune sand as a cement replacement material in precast concrete,thus reducing PC consumption.

The study concluded that partial substitution of PC with GDSin binary blended cement does not significantly affect the freshproperties of the pastes or mortars. However, increasing the GGBScontent leads to an increase in the water required to achieve thenormal consistency, but this has only a minor effect on the settingtime. As the content ofGDS is increased in the binary mixtures, thecompressive strength decreases with standard curing, however, withautoclave curing, the compressive strength is improved. The highestcompressive strength is achieved with 30% of the PC replaced withGDS. All of the binary and ternary blended mixtures develop greatercompressive strength than the CTRL mixture when autoclaved.The combination of 30% GDS + 50% PC + 20:0 GGBS .yieldsthe highest strength under autoclave curing conditions. However,

." 32

the study shows that it is also possible to reduce the PC content byup to 90% by incorporating GDS and GGBS in autoclave-curedmortar mixtures. This finding has significant implications for thesustainability and economy of concrete construction in countrieswith abundant supply of natural dune sands.

CONCLUSIONThis inaugural lecture highlights the increasing importance ofconcrete as a construction material in the contemporary buildingindustry. It also discusses in detail the constituents of concrete,among which is Portland cement, and the ongoing research tofind better and more economical substitute constituents for themanufacture of Portland cement.

In the discussion on concrete and the construction industrythe concept of the Industrialised Building System (IBS) is used asa suitable replacement for conventional construction approachesthat are saddled with problems like shortage of local labour, poortumaround time and economic non-viability.

The IBS is a concept that involves the prefabrication ofconstruction components, modules, interlocking hollow blocksand even heavy concrete slabs off-site, which are later transportedto the building site to be easily and quickly erected or assembled.This does not require highly skilled labour, is cost effective andtime saving.

However, even as concrete continues to be a crucial andintegral component of the construction industry, and the IBS gainsacceptance as a superior construction approach, the search for betterperforming constituents of concrete continues. This is because anyimprovement in the quality and performance of concrete will have awide-ranging impact on the construction industry due to the criticalrole in plays in the industry. And, thus the search continues.
