A Review on Mechanical Properties of Concrete by Partial Replacement of Cement with Eggshell Powder and Fly Ash

Abstract

Carbon dioxide emission has become one of the most serious issues that cause environmental pollution and global warming. Cement is a crucial part of the production of concrete, which is used extensively in construction. In the manufacturing of 1000kg of cement, 900kg of carbon dioxide is produced. In this manufacturing process, the approx. 5% to 7% of total carbon dioxide released on earth is produced from this. Researchers face a significant challenge in reducing the amount of cement used in concrete mixing by substituting waste or environmentally friendly materials. The primary goals of this research are to minimize the cement content of concrete and explore the utilization of waste resources for high strength concrete. Our ecology has been favourably impacted by the production of concrete using green ingredients in place of cement. In this paper, FA (fly ash) and ES (eggshell) powder are used as waste components, and cement is used to partially substitute them in the concrete mix. Up to 40% fly ash and ESP substitution, the compressive and flexural strength of FA and ESP concrete showed higher strength compared to standard concrete. The mechanical characteristics of concrete containing FA and eggshell powder have been studied.
