The eggshell mostly which are waste product is utilized as a substitute of cement as the eggshell consist of Calcium. This research tries to determine the effective utilization of eggshell powder produced by the egg producing company as a partial substitution for the ordinary Portland cement. In this study, 5%, 10%, 15% and 25% of cement is replaced by the eggshell powder by weight. ESP, rich in calcium carbonate, mimics the primary component of cement, potentially enhancing concrete properties. Mechanical and durability characteristics of eggshell powder-based concrete were investigated. Compressive strength test, splitting tensile strength test and sulphate attack test were conducted at curing ages of 7 and 28 days to determine the optimal percentage of replacement by eggshell powder in eggshell powder-based concrete. Keywords: Eggshell powder, cement replacement, concrete, compressive strength, durability, sulphate attack, sustainability.
