ABSTRACT

This study is to investigate the comparisons compressive strength of concrete

with egg albumen and coconut fiber as additive materials in concrete composition

mixture. Four type of samples are prepared which named by 1% egg albumen (EA),

of coconut fiber (CF), 0.5% of egg albumen with 0.5% of coconut fiber (EACF) and

Ordinary Portland Cement (OPC) as a control sample (CC). A total 72 cylinders with

150 mm diameter and 300mm height were prepared in four groups according to

different mix proportions. The composition mixture rate for sand-cement (s/c) ratio is

2.15, water-cement (wk) is 0.60, aggregate-cement (a/c) is 3.10 and target density is

2400kg/rn3. Then, the samples were cured under two curing conditions which were

air and water curing for 7th, 14th and 28th days before testing. The compressive

strength for concrete with egg albumen was 15. 83MPa, while for the concrete with

coconut fiber was 14.78MPa and concrete with both additives materials added was

12.07MPa. The result obtained showed that the concrete with additive material

achieved lower compressive strength than the control samples for water curing

condition. The samples with 1% of egg albumen showed the higher compressive

strength compared to other mixture in both the curing condition. Through the

observation, the concrete mixture with egg albumen showed lower early strength

gain but is satisfying improvement of strength as the time increased. The study

demonstrated that better engineering properties of concrete can be achieved with

proper curing condition and type of additive material added.

CHAPTER 1

INTRODUCTION

1.1 Background of Study

In Malaysia,, Industrial Building System (IBS) was the most popular and widely

used in the building constructions. It had been used to manage the quality and

productivity of construction industry. A requirement of concrete performance due to

rapid development of super high building, larger size and larger span concrete structure

was very important so that the concept of improvement and quality can be achieved. For

this study, the comparison of concrete compressive strength with various natural

additives fiber as reinforcement was conducted to investigate it quality to the

environmental and human living.

According to Amlan K.S and Devdas M. (2000), concrete was defined as a

composite material that consisted essentially of a binding medium, such as a mixture of

Portland cement and water, within which were embedded particles or fragments of

aggregate, usually a combination of fine and coarse aggregate. Concrete was by far the

most versatile and most widely used for construction material worldwide. It could been

2

engineered to satisfy a wide range of performance specifications, unlike other building

materials such as natural stone or steel, which generally had been used in construction.

Furthermore, an ever-expanding population and high rates of economic

development in Malaysia resulted in the generation of vast amount of waste. It was

estimated about 17,000 of waste generated in Peninsular Malaysia which was about

average per capita generation of waste 0.85kg/ cap! day. As a promoting of green

environment area for human living, 3R (reduce, reuse and recycle) concept was

introduced. This green environment issues helps in promoting new source of growth so

as to strengthen and diversity the industrial base. According to the Local Government

Department Ministry of Housing & Local Government Report, about 1 to 5 % of the

generated wastes were reduced, reused, recycled while the remainder was taken to

disposal sites.

Egg albumen which contained of high protein composition would influenced of

the cement properties when biopolymer-added cement composition with egg albumen.

According to Chandra S. et al (1987), proteins used work as air entraining agents in

cement mortar. Steam curing had an adverse effect on the strength of mortar specimens

mixed with protein. Protein addition introduces hydrophobic properties in the cement

mortar.

Md. Hasim (2005) stated that the used of coconut fiber from the dispose of

coconut shell could be a valuable material in the formation of a composite material that

can be used as an internal panel wall in housing construction.

As such, a new material for construction industry with composition materials of

cement, natural additive fiber (egg albumen and coconut fiber), water, fine sand and

coarse aggregate were developed to investigate the performance of concrete due to it

compressive strength under EuroCode Standard (EN 1992-1-2: 2004)

12 Problem Statement

A production of building with higher strength, lightweight, higher toughness and

others will be the main reason for constructing the building in Malaysia. Nowadays,

problems occur due to deterioration of concrete which caused by interior materials was

leaded to the failure of the building happened in concrete construction. As a result, a

new development of concrete composition with natural additives was introduced in

construction industry. Chandra S. et al (1987) reported that type of additive used would

be influence the strength of concrete when added to concrete mixture.

Nowadays, large amounts of waste natural organic material such as egg albumen

and coconut fiber were disposed in Malaysia. If the waste could not been disposed

properly it would leaded to environmental problems. Recycling of the disposed material

was one of the methods of treating the agricultural waste.

1.5 Significance of Study

This study was conducted to study the advantages of using additive material (egg

albumen and coconut fiber) added to the concrete composition mixture. The advantages

of using the concrete and natural material was discussed in term of the ultimate strength

which corresponding to the compressive strength. Other engineering behaviors that

discussed were included with its workability.

As a egg albumen and coconut fiber act as a additive material for concrete

mixture, this study was determine the different behaviors of different proportion additive

material that can produce the better quality of concrete. This study also used to

determine the best additive materials to be added to concrete mix proportion that would

fit the entire characteristic needed in designing concrete.

Furthermore, this was study carried out in order to determine the comparison

compressive strength of different proportion which was the strength development for 7th, 14th and 28th of curing for the all mix proportion of the concrete. The results that been

obtained from experimental works were used for future study such as lightweight

concrete with natural organic material as a new structure element in the construction

activity.

1.6 Summary

The usage of concrete with natural waste material for cementitious material

commonly gave a lot of advantages. In this day and age, construction was looking

forward for a high strength with low water-to-cement ratio, durability with low

permeability, minimum cement content and proper mixing, compaction and curing, high

quality, high performance and but in an optimum quantity for overall cost. As by using

concrete, all of these characteristics and benefits may be achieved. Natural additive

materials were able to increase the strength of concrete when mixed together. Plus, it

was been superior environmental friendliness due to ecological disposal of large

quantities of waste materials (the solid waste or organic waste) were reduced and

enhancement productivity of the construction industry.

LITERATURE REVIEW

2.1 Introduction

The purpose of studying a literature review was to find, read, and analyze the

body of literature which been published by books, journal article, conference articles,

research papers and thesis. Previous reviews on engineering properties of concrete and it

performance in the existing applications will be studied in order to analyze more

valuable information associated to the construction activity. In this chapter, the review

on waste material such as egg albumen, and coconut fiber also were analyzed.

2.2 Introduction to Concrete

Concrete was a name applied to any of a number of compositions consisting of

sand, gravel, crushed stone, or other coarse material, bound together with various kinds

of cementitious materials, such as lime or cements. When water was added, the mix

undergoes a chemical reaction and hardens. The word concrete comes from the Latin

word "concretus", which means "headened" or "hard". Concrete has been used in

construction for over 2000 years, perhaps first by the Romans in their aqueducts and

roadways. According to Nan Su and Buquan Miao (2003), concrete was the dominant

construction material today with an annual worldwide production of cover 4.5 billions

metric tons.

2.3 Historical Development of Concrete

Anonymous said that the Romans found that the mixture of lime putty with

pozzolana, a fine volcanic ash, would harden under water. The result was possibly the

first hydraulic cement. It became a major feature of Roman building practice, and was

used in many buildings and engineering projects such as bridges and aqueducts.

Concrete technology was kept alive during the Middle Ages in Spain and Africa, with

the Spanish introducing a form of concrete to the New World in the first decades of the

16th century. It was used by both the Spanish and English in coastal areas stretching

from Florida to South Carolina. Called .tapia., or .tabby., the substance was a creamy-

white, monolithic masonry material composed of lime, sand, and an aggregate of shells,

gravel, or stone mixed with water. Concrete was widely used in domestic, commercial,

recreational, rural and educational construction.

Un-reinforced concrete was a composite material containing aggregates (sand,

gravel, crushed shell, or rock) held together by a cement combined with water to form a

12

paste It gets its name from the fact that it does not have any iron or steel reinforcing

bars. It was the earliest form of concrete. The ingredients become a plastic mass that

hardens as the concrete hydrates, or .cures. While for the reinforced concrete was

concrete strengthened by the inclusion of metal bars, which increase the tensile strength

of concrete. Both un-reinforced and reinforced concrete can be either cast in place or

pre-cast.

2.4 Advantages and Disadvantages of Concrete

Concrete definitely presents technological advantages: it can be made from local

inexpensive materials and it can be cast in a any shape. Concrete has a good

compressive strength, it does not rot, it was not much affected by humidity, it does not

burn and it was not attacked by insects (but it can be attacked by certain bacteria).

Moreover, when concrete was well proportioned, adequately mixed, transported, placed

and cured, it becomes a durable construction material in most environmental conditions.

Concrete technology was simple: it consists essentially in thoroughly mixing a fine

powder with aggregates, water and admixtures and in compacting of this freshly mixed

material into forms where it takes its final hardened shape and strength within less than a

day.

Concrete also presents some weakness: it was weak in tension, it was heavy, it

was not volumetrically stable because it shrinks and creeps or sometimes swells.

Moreover, concrete must be properly cured to reach its full potential as a structural

material, and its durability can be impaired in severe environmental conditions, usually

acidic conditions which stated by Baron and 011ivier (1992). Today, some of these

weaknesses have been partially overcome with reinforcing bars, fibres, admixtures and lightweight aggregates.

13

As concrete's advantages out-weight its weakness, it was not surprising that

concrete was presently the most widely used material after water. According to Syndicat

Francais de I'Industrie Cimentiere (1998), every year more than 1.5 billion tonnes of

cement were produced. From this huge amount of cement, around 6 billion cubic metres

of concrete were made. Moreover, ACI Committee 125 stated that concrete can be made

from the equator to the poles, in the desert, on the sea, under water and even on he Moon.

It was so successful a material that was can be considered as the basis on which our

present civilization has been built.

2.5 Properties of Fresh Concrete

The performance requirements of hardened concrete were more or less well

defined with respect to shape, finish, strength, durability, shrinkage and creep. To

achieve these objectives economically, the fresh concrete, in addition to having a

suitable composition in terms of quality and quantity of cement, aggregates and

admixtures, should satisfy a number of requirements from the mixing stage till it was

transported, placed in formwork and compacted.

The mix should be able to produce a homogenous fresh concrete form the

constituent materials of the batch under the action of the mixing forces. The mix should

be stable, in that it should not segregate during transportation and placing when it was

subjected to forces during handling operations of limited nature. Beside that, the mixture

should be cohesive and sufficiently mobile to be placed in the form around the reinforcement and should be able to cast into required shape without losing continuity or homogeneity under the available techniques of placing the concrete at the particular job

which termed as fiowability and mobility for of fresh concrete. Besides that, it can be be

ameable to proper and thorough compaction into a dense, compact concrete with

minimum voids under the existing facilities of compaction at the laboratory work or site.

Lastly, it should be possible to attain a satisfactory surface finish without honeycombing

14

or blowing holes from moulds and on free surface by trowelling and other process which

namely by finishing. These entire requirements were affected of the workability of the

concrete.

2.5.1 Workability of Concrete

Workability defined as that property of freshly mixed concrete or mortar which

determined the ease and homogeneity with which it can be mixed, placed, compacted

and finished. A slump test can be used to measure the workability of concrete. The

workability was affected by the amount of cement paste added. The cement paste was

the soft or liquid part of the concrete mix. The more mixed with the coarse and fine

aggregates, the more workable a mix. Furthermore, it's also affected by the aggregate

grading. Well- graded, smooth, rounded aggregates will improve the workability of a

mix. An additional water to the concrete mixture will lead to the lowers the strength and

durability of the concrete

The workability was affected by the mix proportions of the mixtures, aggregate

properties, admixtures, environmental conditions and time.

2.6 Properties of Hardened Concrete

The main properties of hardened concrete were early volume change, creep, and Permeability.
