A Study to Produce Suistainable Concrete using Egg Shell Powder and GGBS

Throughout the world, concrete is widely used for the construction of most of the buildings, bridges etc. To meet this rapid infrastructure development a huge quantity of concrete is required. To make the production of cement sustainable, the whole construction industry is in search of a economical, eco-friendly and effective the waste product that would minimize the use of cements. The pressure to reach sustainability favors the development of ternary composite cement some of such supplementary cementacious material (SCM) has already been identified like Fly Ash, Silica Fumes, Rice Husk Ash (RHA), Egg shell etc.The synergistic effect on mechanical behavior at 28 days between EGG SHELL POWDER and pozzolanic additives like BLAST FURNACE SLAG (BFS), has been documented. In order to better understand the synergistic effect, this article investigated the effect of egg shell powder on the microstructure of cement-slag cementitious system.
