A Review on Partial Replacement of Cement by Egg shell Powder

Abstract
The use of SCM‟s was done from the ancient Greeks who incorporated volcanic ash with hydraulic lime to create acementitious mortar. The Greeks passed this knowledge on to the Romans, who constructed such engineering marvels as the Roman aqueducts and the Coliseum, which still stand today. Early SCMs consisted of natural, readily available materials such as volcanic ash. Nowadays, most concrete mixture contains supplementary cementitious material that forms part of the cementitious component. These materials are majority byproducts from other processes or natural materials. The major benefits of SCM is its ability to replace certain amount of Portland cement and still able to display cementitious property, thus reducing the cost of using Portland cement. More recently, strict air-pollution controls and regulations have produced an abundance of industrial byproducts that can be used as supplementary cementitious materials such as Pozzocrete, Saw dust ash, Rice husk ash, Egg shell powder, Sugarcane bagasse ash, etc. The use of such byproducts in concrete construction not only prevents these products from being land-filled but also enhances the properties of concrete in the fresh and hardened states. This paper presents a brief history and review of Egg shell powder in concrete with the aim of introducing the technology. Keywords - Cement Replacing Material, Egg Shell Powder, Compressive Strength
