Abstract

Eggshell (ES) is a bio-waste material commonly generated by bakers and fast-food restaurants. Typically, this waste is discarded in landfills, posing health risks and contributing to environmental pollution. However, eggshell waste contains valuable organic and inorganic materials that can be composted with other substances to improve their properties. In the civil sector, the primary objective is efficient construction with minimal cost. Cement, a crucial component of construction, is the backbone of infrastructure development. However, cement plants are the source of a few harmful compounds like carbon dioxide (CO2), Sulphur dioxide (SO2) and Carbon monoxide (CO) which can cause serious health defects and also affect our environment. The cement manufacturing sector is the third largest contributor to environmental pollution. Despite this, there is a significant demand for various types of cement to support national development. This rising demand has driven the search for alternative raw materials derived from abundant waste products that are both efficient and cost-effective. To mitigate the impact of harmful compounds and protect the environment, eggshell powder is used as a partial replacement for cement. This study examines the effects on concrete properties when cement is replaced with 5%, 7.5%, and 10% eggshell powder. The properties were experimentally assessed based on compressive strength and split tensile strength. These strengths are measured at 7, 14, and 28 days and compared with conventional concrete. The results indicate that 7.5% eggshell powder is the optimal percentage for partial cement replacement. In conclusion, Eggshell powder could be utilized in future construction materials to reduce carbon dioxide emissions and promote sustainability.
