Abstract—Environmental concerns due to the over-exploitation of sand have led to

restrictions onextraction of sand across India. Thus, the construction industry has huge

demand for a suitable environmentally friendly alternative to sand. On the other hand,

recycling of waste plastic is rarely done in India, with nearly 40% left in landfill. The

dumping of these plastic materials, which degrade at extremely low rates, will lead to high

negative impacts in the society. These plastic wastes will persist in the environment for

very longer period, which is a long-term environmental concern. In order to solve both

these problems, processing the waste and using it as a partial replacement of sand can be

done. As there is strength degradation observed in various previous studies of plastic

incorporation in concrete, Rise Husk Ash (RHA) and Silica Fume (SF) are replaced for

cement to enhance the strength. Keeping the RHA and SF proportion to be constant, the

maximum amount of plastic waste that can be replaced for sand is found out. This paper

mainly focuses on the mechanical behavior of the plastic impregnated concrete. The result

concludes that the maximum amount of plastic that can be partially replaced for sand in

concrete is 30%. Beyond that, the concrete will not satisfy the minimum requirements of

the codal provisions.

Abstract - Now a day’s construction field facing many problems, one of them is scarcity

of water. Proper curing is not practically possible in most of the cases. So, the concept self

curing distributes the extra curing water (uniformly) throughout the entire 3-D concrete

microstructure. Self curing agent is more readily available to maintain the saturation of the

cement paste during hydration and reducing the autogenous shrinkage. The aim of the

project is to investigate the strength characteristics i.e compressive strength, split tensile

strength and flexural strength of self curing concrete with silica fume using sodium

polyacrylate and to eliminate the shrinkage effect. The grade of the concrete selected was

M30. Self curing agent used is sodium polyacrylate (0.2, 0.3% and 0.4%) relative to

cement mass. Partial replacement of cement with silica fumes 10% to increase the

pozzolanic properties of the concrete. The optimum mix ratio is taken for the casting of

beam and the flexural strength characteristics was studied and compared with the control

mix.

Key words: Self curing, Sodium polyacrylate, Silica fume, flexural strength.

Abstract— In larger constructions, such as in construction of bridges and buildings, steel-

concrete composite structures are employed to provide high strength and stiffness. These

composite structures function based on the commonly- known fact that concrete is weak in

tension but strong in compression. A natural consequence of this composite action is the

shear flow between the concrete and the steel. In order to prevent slip from occurring

between the concrete and steel sections, shear connectors are provided, thereby allowing

the two components to behave as one1. The focus of this study is on shear connectors of

the flexible type, which resist shear forces by bending, tension or shearing at the point of

connection between the connector and the steel beam. The steel concrete composite

construction has become an effective construction practice in the recent years. The cold

form profiled sheet acts a platform for during the construction phase and acts as an external

reinforcement after the construction. In steel concrete composite construction, the shear

connectors transfer the longitudinal shear force across the steel flange/concrete interface.

The ability to transfer the longitudinal shear force by shear connectors mainly depends on

the strength of concrete against longitudinal cracking and mechanical properties of the

shear connectors. Head stud and L-shaped shear connectors will be used and tested in this

project.

Keywords— Composite slab, Shear connectors, Cold form steel sheet, Head stud

Abstract— Concrete is the most widely used construction material in Civil

Engineering industry because of its high structural strength and stability. The main

ingredient in the conventional concrete is Portland cement. The amount of cement

production emits approximately equal amount of carbon dioxide into the atmosphere.

GROUND GRANULATED BLAST SLAG (GGBS) is a new mineral admixture, whose

potential is not fully utilized. Blast Furnace slag has been used extensively as a successful

replacement material for Portland cement in concrete materials. M30 grade concrete are

used. Vermiculite extremely has low density and thermal conductivity continue to use in

concrete over other filler materials. Various mix combinations with a partial replacement

of 25% and 30%, 40% by GGBS and Vermiculite. This replacement had proved to have

some economic benefits as well as time effective in concreting for the future. Vermiculite

in concrete that can be used for improving shrinkage, crack resistance, fire resistance and

reduces environmental impact and also reduce the cost. The concrete cubes are cast and

test for compressive strength after curing period of 7 &28 days.The integrated approach of

working on safe disposal and utilization can lead to advantageous effects on the ecology

and environmental also.

Abstract—This paper presents comparison of bonding strength and compressive strength

between steel and concrete. The bond strength measures the effectiveness of the grip

between concrete and steel.In pullout tests on Mild steel bars , the maximum load

generally represents the bond strength that can be developed between concrete and

steel.With Mild steel bars the maximum load is not very different from the load at the

visible slip,But in the case of deformed bar,the maximum load may corresponds to a large

slip which may not be obtained in practice before other type of failure occur.It is preferable

therefore than comparing plain and deformed bar determined not only the maximum

load,But also the load arbitrary amount of slip and also plot the complete load slip curves

for the plain and deformed bar under comparison.In bonding strength test,comparison of

the load at a relative movement(slip) between steel and concrete of 0.125mm at the free

end of the bar in a pullout test. The analysis of the test data shows that a significant co-

relation exists between the compressive strength of cube cured under standard conditions

and the bonding strength of concrete.

industry, especially in residential, commercial and industrial buildings. In recent times, the

use of cold formed high strength steel members has rapidly increased. Cold formed steel

(CFS) cross sections can be optimized to increase their load carrying capacity, leading to

more efficient and economical structural systems. Buildings framed from cold formed steel

members are becoming increasingly common. Significant research has been conducted on

individual cold formed steel members, due to the open nature of the sections, torsion

induces warping in the beam. This paper summarizes the research on the behavior of cold-

formed steel beams subject to torsion. The attention is focused on beams subject to torque,

Abstract-Geopolymers are materials based on pure alumino-silicate source materials such

as fly ash; granulated blast furnace slag obtained from industrial, activated with either with

the combination of sodium silicate and sodium hydroxide or with the combination of

potassium hydroxide and potassium silicate. High alkaline solutions are used to induce the

silicon and aluminum atoms in the source material to dissolve and form Geopolymer gel.

The sol gel formation (or polymerization) may be assisted by application of heat, followed

by drying. The usage of ground granulated blast furnace slug made the geopolymer motor

to cure at the room temperature. The Geopolymer gel binds the loose coarse aggregate, fine

aggregate and unreacted source material to form Geopolymer composites. The Portland

cement free Geopolymer composites have many advantages like less curing time, earlier

development of higher mechanical strength, very little drying shrinkage and very low

creep, excellent resistance to sulfate attack, good acid resistance and resistance to high

temperature. The strength development in Geopolymer composites depends on the

chemical composition, morphology and reactivity of source materials, chemical

composition of activating solution and curing process. The Geopolymer with the

combination of mesh increase the compressive strength of the concrete.

Abstract -Conventional brick is the most basic building material for the major

construction of structures. Due to rapid growth and development in the construction field,

Civil Engineers are in search for a new building material and techniques on the basis of

economy, durability and efficiency which serves as an alternative for the conventional

brick. The change in the masonry system is due to the factors like reduction in man power

and speed of construction. This investigation compares the conventional brick and fly ash

based interlockingblock on the basis of structural aspects such as Compressive strength,

Impact resistance, Energy absorption and Bond strength. Interlocking block gives the

better results on strength and durability when compared with conventional brick. The

compressive strength of the interlocking block increases by 15% to 20% when compared

with conventional brick. The bond strength of interlocking block is greater than the

conventional brick. The interlocking block can withstand temperature more than that of

nominal brick. The interlocking block has been utilized in both load bearing and non –

load bearing masonry system.

that contribute to environmental pollution. One solution to environmental pollution

includes recycling these plastic wastes as synthetic fibre and incorporating them into

concrete. This research aims to investigate and evaluate the performance of concrete using

waste plastics. Waste plastic bottles, coffee straw and outer casing insulation of electrical

wire are used in this project and fly ash is being used as a partial replacement for cement.

The waste plastics are taken in a ratio of 1%, 1.5% and 2% respectively to the weight of

cement. Their properties are tested to study the characteristic strength, split tensile and

flexural strength and to find optimal utilization of these waste plastics without modifying

its nature. Results indicate that an increase in fiber volume improves tensile strength of

concrete. Incorporation of high-volume fiber with concrete results in a substantial amount

of fibres bridging and crossing the fractured sections, thereby activating failure resistance

mechanisms

Abstract-The global use of concrete is second only to water. As the demand for concrete

as a construction material increases, so also the demand for Portland cement. The global

warming is caused by the emission of greenhouse gases, such as carbon dioxide (CO2), to

the atmosphere by human activities. Among the greenhouse gases, CO2 contributes about

65% of global warming. In terms of global warming, the geopolymer technology could

significantly reduce the CO2 emission to the atmosphere caused by the cement industries.

The Geopolymer gel binds the loose coarse aggregate, fine aggregate and unreacted source

material to form Geopolymer composites. The Portland cement free Geopolymer

composites have many advantages like less curing time, earlier development of higher

mechanical strength, very little drying shrinkage and very low creep, excellent resistance to

sulphate attack, good acid resistance and resistance to high temperature. The concrete

cubes are made by varying the fly-ash content by 500 kg/m3,450 kg/m3, 400 kg/m3. The

Geopolymer with the combination of mesh in different layers such as 1 layer, 2 layer and 3

layers increases the compressive strength of the concrete as well as mortar and the

combination of 3 layers in concrete provides maximum results in compression strength.

Abstract—Numerous natural issues are related with thecreation of Ordinary Portland

cement. Vast measure of thecarbon dioxide discharges amid the assembling of

OrdinaryPortland cement because of the calcinations on limestone andignition on non-

renewable energy source is in the request ofone ton for each ton of OPC created. The

degree of vitalityrequired to create Ordinary Portland cement is just by steel.On the second

face the copious accessibility of fly ash overallmakes chance to utilize this side-effect of

consuming coal, as asubstitute for Ordinary Portland bond to fabricate concrete.Hence, one

of the approaches to create ecological invitingconcrete called Geopolymer, is to lessen the

utilization ofOrdinary Portland Cement by utilizing different types ofbinders to make

concrete. In geo-polymer concrete, the GGBSand silicon and the aluminium in the low-

calcium (Class F) flyash respond with a alkaline activator that is a mix of sodiumsilicate

and sodium hydroxide solutions for structure theGeopolymer that binds the aggregates and

other unreactedmaterials. Geopolymer concrete carries on like conventionalconcrete yet

have slight increment in strength and significantincrement in twisting properties.

Geopolymer concrete is 25percent monetarily valuable than standard concrete. Fly

ashsubstance of 500 Kg/m3, 450 Kg/m3 and 400 Kg/m3 are trailedin Geopolymer

concrete. From which the fly ash content of 400Kg/m3 gives the more strength and

workability whencontrasted with conventional concrete.

Abstract-The open holed plates are widely used in bolted connections and are made of

aluminum, steel, cold formed steel structures and FRP composites. The presence of these

perforated holes in structural members may complicate the design process. Thus, the

industry needs simplified local buckling prediction methods for predicting the elastic

critical stress and load deformation response. The perforated plates when subjected to

compression experience buckling and instability. The presence of slots may create unique

buckling modes and can either increase or decrease the plate’s critical elastic buckling

stress based on the geometry, shape and pattern of the holes and their spacing. This

research would explore the possible buckling failure modes, elastic stiffness, elastic critical

stress, elastic buckling behaviour, Stress intensity factor and load deformation response of

cold formed stainless steel plates and FRP composites for varied load conditions, shape,

size, geometry, aspect ratio and pattern of perforated plates using Eigen value buckling

analysis by finite element modelling.Thebehaviour of plates would be analysed for four

loading cases including concentrated edge loading, asymmetric partial loading at opposite

edges, partial loading at the centre of opposite edges and partial loading at the two ends of

the opposite edges.

Abstract -Ferrocement is a type of thin wall reinforced concrete reinforced with closely

spaced layersof continuous and relatively small size wire mesh. The mesh may be made of

metallic orother suitable materials. Mortar provides the mass and wire mesh imparts tensile

strength andductility. This paper presents an experimental and analytical investigation to

compare theflexural behaviour of partially replaced metakaolin and fly ash with control

ferrocements.Inclusion of metakaolin in ferrocement matrix influences properties of the

mortar. Fly ash isone of the residues from thermal powerplant which makes mortar more

durable. Themetakaolin-fly ash mortars with 15% metakaolin and 5-25% of fly ash

replacement in theincrements of 5% with cement were made. Constant water to

cementitious ratio of 0.5maintained for all mortars. The control ferrocement has no

replacement of fly ash andmetakaolin. Galvanized hexagonal steel wire meshes were used

as mesh reinforcement.Ferrocement panel size of 470 mm x 940 mm,40 mm thickness has

been adopted.First phase of work carries analytical work done by ANSYS® Workbench

18.2. In this phase,the work has been carried out to show the variation between

conventional panel andferrocement panel. Further in second phase, the flexural strength of

the ferrocement panel hasbeen studied by casting mortar cubes followed by panel casting

Abstract-In precast structures, achieving the monolithic behavior of the joint is the

majorproblem faced by the engineers. One of the effective and possible solutions is

creating anovel joint. In order to model a novel joint, various failure modes are studied and

the joint isdesigned in such a way that it can sustain all the failures in an enhanced manner.

Themodeling of the precast joint in the ABAQUS involves simulation of long bolts, base

plates,surface stiffener plates and hyper-elastic materials and assembling them. Contact

models areprovided in order to ensure the contact between the regions and interaction data

are fed todefine the degree of contact between the materials. The response of the novel

precast beam-column joint as well as the conventional beam-column joint is analyzed

under cyclic loadingand the results are compared. The results depict that energy dissipation

capacity, stiffnessdegradation and ductility ratio of both the precast joint and conventional

joint are nearlysimilar. Thus, the designed precast joint was found to be a significant

solution for achievingthe monolithic behaviour, which makes it to have better applicability

in the seismic regions.

Abstract- Concrete is the most important construction material. Among all these

ingredients,fine aggregate plays the major role in concrete. In present era, the availability

of natural sandis very less. To overcome this problem we could use alternative material,

i.e. waste materialslike crumb rubber. The disposal of waste crumb rubber has shown an

adverse impact on theecological balance causing pollution all over the world. In such a

case, an alternative solutionfor the use of rubber and their products is to incorporate it into

concrete, as a partialreplacement to natural fine aggregate. The use of crumb rubber in

construction is increasing.Concrete mixed with crumb rubber has better toughness than the

ordinary concrete, and alsohas a better heat insulation and sound insulation properties and

better energy absorption.Rubber mixed with concrete increases the workability but

decreases the mechanicalproperties including compressive strength, split tensile strength

and flexural strength. In orderto overcome this problem we have to use treated rubber,

GGBS, and silica fume. The silicafume and GGBS when mixed with concrete increasing

the strength.

Abstract-Self-compacting concrete (SCC) is a stable and cohesive high consistency

concrete mix with enhanced filling ability properties that reduce the need for mechanical

compaction. Day by day due to scarcity of raw materials for concrete there is a need to find

the alternate solution for conserving raw materials by using alternate materials. The use of

quartz sand as replacement for sand is an economical solution for making the concrete.

This paper aims to focus corrosion study of self-compacting concrete made with industrial

wastes, i.e., marble sludge powder(MSP) and quartz sand(QS).MSP can be used as a filler

and it helps to reduce total voids content in concrete and the usage of quartz sand is

proposed as partial replacement of fine aggregate in production of SCC. The main purpose

of this paper establishes the optimum percentage of replacement of quartz sand and marble

powder in order to obtain high strength.

Abstract−

Now a day’s construction field facing many problems one of them is

scarcity of water. Proper curing is not practically possible in most of the cases. So, the

concept self curing distributes the extra curing water (uniformly) throughout the entire 3-D

concrete microstructure so that it is more readily available to maintain the saturation of the

cement paste during hydration and reducing the autogenous shrinkage. The objective of

the project is to investigate the strength characteristics of self curing concrete with silica

fume incorporating different chemical curing agent and to eliminate the shrinkage effect.

The grade of concrete selected was M25.The self curing agents used is polyethylene

glycol-6000 (0.5%, 1% and 1.5%) relative to cement mass. The optimum mix ratio is taken

for the casting of beam and the strength characteristics will be studied and compared with

the control mix. The effect of variation in strength parameters, elastic properties and

shrinkage i.e., Compressive Strength were studied for different dosage of self curing agent

and shrinkage reducing agent PEG in order to reduce early-age shrinkage and at the same

time, maintains the mechanical properties and durability of concrete.
