Abstract

Abstract: The recycling of solid wastes is an important goal for sustainability in order to preserve natural resources for future generations. The construction industry is the prime sector for consuming the highest amount of natural resources. Eggshell powder (ESP) is a bio-waste product and also a potential material for replacing cement while making green concrete. This eliminates the impact of disposal of eggshells in landfill on the environment. Eggshell powder is rich in calcium oxide content and ignites the researcher to substitute for cement in concrete production. This review report presents the suitability of ESP in high strength concrete with respect to the structural and durability performance observed from research findings. Based on the evidence collected from numerous research publications, it may be concluded that 8–10% replacement of cement is possible without compromising the mechanical strength and structural performance and it increases the hydration process during the early periods. However, the ESP had shown a negative impact on durability properties, particularly in the chemical environment, and needs further investigations in this regard. The results obtained from various sources are reviewed and highlighted in this paper.
