The performance of eggshell powder as an additive concrete mixed

In this developing world, many countries are going to urbanization due to population
growth. Since Malaysia is one of developing countries, the construction will grow in the
future. Chicken egg is one of the waste materials which generated from the industry and
it is contributed to the environmental and disposal problem due to eggshell increase
continuously in recent years. Therefore, reuse eggshell as an additive in concrete is a
better solution to reduce the environmental problem. The experiments were carried out
into four proportions which are 0%,
5%,
10%, and
15%.
These eggshells must be
grinded into fine powder. The objective of the experiment is to determine the
performance of eggshell powder in term of its strength. The experiments were used to
investigate the eggshell is slump test, compressive strength test, flexural test and water
penetration test respectively. From the results, eggshell powder in 5% additive in
concrete has a good compressive strength which is 28.87.N/mm
compared with the
others proportion. Furthermore, it also improved in flexural strength in all additive
2
proportions. The results show eggshell powder has a best performance in water
penetration test which is 11.5 mm in depth. The findings suggested that the suitability of
eggshell powder with different proportions is applicable in the structural system of the
buildings.
