Abstract: “In this paper, eggshell waste from a pullulating chick hatched eggs farm was used to study the effect of substituted mortar mixing water by eggshell powder solution (ESPS). ESPS were made by dissolving 5%, 10%, 15%, 20%, 30% and 40% by weight of eggshell Concentrations in water by boiling. The microstructure and chemical composition were displayed. The physical and mechanical properties of ESPS cement mortar were experimentally studied at 2, 7 and 28 days of curing. X-Ray Diffraction patterns for eggshell powder displayed that the major component in eggshell powder is calcium carbonate (CaCO3) in calcite form. The study showed that both workability and density were decreased with the increasing of ESPS concentration. The results indicated an improvement in both compressive and flexural strengths at 10% inclusion ESPS concentration.”

Keywords: Eggshell powder, cement mortar, workability, compressive strength, Flexural strength.
