2018-7-8  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, fast-food restaurant among others which can litter the environment and consequently constituting environmental problems or pollution which would require proper handling. In the ever increasing efforts to convert waste to wealth, the efficacy of converting eggshell to beneficial use becomes an idea worth embracing. The composition of eggshells indicates that the effect of it ash on cement treated materials should be articulated. It is scientifically known that the eggshell is mainly composed of compounds of calcium which is very similar to the cement. Literature has shown that the eggshell ash primarily contains lime, calcium and protein where it can be used as an alternative raw material in the production of wall tile material, concrete, cement paste and others. Eggshell also contribute to construction industry which is it can be reduce in construction cost and landfill which it give good performance in properties in concrete and durability of the concrete. Thus, eggshells
