The use of SCM's was done from the out of date Greeks who solidified volcanic powder with water driven lime to make a cementitious mortar. The Greeks passed this learning on to the Romans, who manufactured such structuring marvels as the Roman water channels and the Coliseum, which still stand today. Early SCMs contained typical, immediately open materials, for instance, volcanic red hot flotsam and jetsam. Nowadays, most strong mix contains profitable cementitious material that structures some bit of the cementitious portion. These materials are bigger part reactions from various methodology or customary materials. The noteworthy focal points of SCM is its ability to supersede certain proportion of Portland concrete and still prepared to indicate cementitious property, subsequently decreasing the cost of using Portland bond. Even more starting late, extreme air-pollution controls and rules have conveyed an abundance of present day symptoms that can be used as favorable cementitious materials, for instance, Pozzocrete, Saw buildup blazing remains, Rice husk slag, Egg shell powder, Sugarcane bagasse ash, etc. The usage of such symptoms in strong advancement not simply shields these things from being land-filled at this point moreover improves the properties of bond in the fresh and set states. This paper shows a compact history and review of Egg shell powder in bond with the purpose of displaying the development
