Flexural Performance of RC Beam with the Partial Replacement of Cement with EggshellPowder(ESP)

Abstract

Abstract: It's a renowned fact that concrete used around the globe is second only to water. The cement industries have been categorized as highly polluting industries by the Central Pollution Control Board (CPCB). The production of ordinary Portland cement contributes 5-7% of total greenhouse gas emission and also consumes large amount of energy, hence it is crucial to discover substitute to cement. Eggshell is a waste material that can be obtained from restaurants, bakeries and households. Eggshell powder (ESP) has high amounts of calcium and can be combined with pozzolanic materials, such as fly ash, which have low calcium content. If effective uses for eggshell can be found, it would create an opportunity for a sustainable solution. Eggshell waste is among the most abundant agro-waste material discharged from food processing industries. Despite the exceptional properties and several applications, eggshell is castoff in huge quantity without any further use. This review paper focuses on appraising the potential uses of eggshell waste as a feedstock for production of sustainable construction materials. The emphasis is on the need to exploit extensively eggshell waste as a partial cement replacement material in cement-based construction materials. This study focuses on the viability of using calcined eggshells (CES) as a partial replacement of cement by analysing early age performance. Compressive, Flexural and Split Tensile Strength of concrete with 10%, 15%, 20% cement replacement with eggshell powder. The utilization of PES which offers a low-cost and energy-efficient resource for construction.
