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.
An investigation of eggshell powder as potential additive to concrete. In this investigation, five different percentages of eggshell powder with respect to cement were added into the concrete mix
Table 1: Classification of concrete in accordance with unit weight Source: Zongjin Li (2011) This research paper discusses the use of egg shell as an alternative fine aggregate to the more conventional granite/gravel. Eggshells are agricultural throw away objects produced from
An investigation on the performance of eggshell in concrete has been tested and carried out. Four proportions of concrete specimens were used in this research which is 0%, 5%, 10%, and 15%. In this concrete the material was used are Portland cement, chicken eggshell, coarse aggregate, fine aggregate, and optimum of water. The maximum size of the coarse aggregate is 20 mm and sizes of
#0183;#32;They may have been using the eggshells as an additional source for Calcium for the cement paste. Eggshells are rich in CaCO3, and some modern research is into using egg shell ash as an additive to increase concrete strength, and as an accelerator to speed curing.

One pdf file outlines some research into using it for roadbed construction:
Earlier works on the combination concrete conducted by scholars have led us to the point that the eggshell ash can be used as an additive in concrete production. Eggshells are agricultural waste materials generated from chick hatcheries, bakeries, and fastfood restaurant among others which can

A experimental study of natural admixture effect on . A experimental study of natural admixture effect on conventional concrete and high volume class F flyash blended concrete Class F fly ash (FA) was used as an additive The properties of Class F fly ash are showed in Table 3 (approximately 18 eggs per m 3 of concrete) Table 16 Cost analysis of C 100_FA 0 and C 45_FA 55 mix C 100_FA
Freezing reduces strength of concrete by 20 to 40 % when fresh concrete is subjected to freezing. Antifreeze admixtures of concrete, its properties and uses in cold weather concreting are discussed. The resistance of the fresh concrete against the freeze and thaw cycle is given by the durability factor which is also lowered by 40 []
Various types of admixtures are used in concrete to enhance the performance of concrete. Concrete admixture is defined as the material other than the aggregate, water and cement added to the concrete. Types of Concrete Admixtures Concrete admixtures are of different types and

in concrete mixture. The egg shells are mixed into the concrete as filler up to 20%. The performance of concrete mixture is defined though slump test, compressive strength test, flexural test, water absorption test and water penetration test. Keywords Egg shell, concrete filler, waste management Biography
The concrete specimens were tested in the series of compression test to determine the strength of concrete for 3, 7 and 28 days. As a result, the additional of eggshells ash to the concrete mix increase the strength of the concrete. In short, the higher percentage of eggshells ash in the mix means a higher compressive strength for the concrete.
This paper describes research into use of poultry waste in concrete through the development of concrete incorporating eggshell powder (ESP). Different ESP concretes were developed by replacing 5
Besides that, concrete with 5% eggshell additive achieve the highest compressive strength which is 28 N/mm2. The eggshell concrete also improves in flexural strength which is the highest strength is N/mm2 and water penetration test produce a best of performance with lower depth at 14 mm only.
Apart from these studies, no other investigations were found in literature to use eggshells in civil engineering applications. Therefore, to initiate use of eggshell waste for partial replacement of cement in concrete, there is a need to understand concrete properties made
