Abstract: The purpose of the study is to assess the combined impact of eggshell powder (ESP) and fly ash (Class F) and rice husk ash (RHA) as additional cementitious materials in concrete applications. Fly ash is widely used in concrete works due to its ability to improve mortar and concrete properties. The usage of eggshells, a biodegradable waste product from bakeries, fast food establishments, and chick hatcheries, is also examined in this study. It assesses the fly ash-f, RHA, and ESP blended cements' chemical makeup, physical characteristics, consistency, beginning and final setting times, pH level, and compressive strength. The strength property of ESP blended cement mortars is also evaluated. The study also compares the strength properties of ESP concrete mixes and a control mix. The study also assesses the coefficient of water absorption, sorptivity, resistance to chloride ion penetration, and diffusion coefficient. The findings will help determine how much fly ash and rice husk ash should be replaced in concrete.
