Partial Replacement of Cement Using Rice Husk Ash and Eggshell Powder

Abstract

Concrete specimens are determined by replacing cement with rice husk ash and eggshell powder. This approach is part of sustainable construction practices where waste products are utilized to reduce the reliance on traditional materials like cement, which has a significant environmental impact due to its production process. Rice husk ash is a byproduct of rice milling and has pozzolanic properties, which can enhance the strength and durability of concrete when used as a partial replacement for cement. Eggshell powder, on the other hand, contains calcium carbonate, which can also contribute to the strength of concrete. When using waste products like rice husk ash and eggshell powder in concrete mixtures, it is important to conduct thorough testing to evaluate the mechanical properties of the resulting concrete. Compressive strength, split tensile strength, and flexural strength are key indicators of the performance of concrete in structural applications. The research study you mentioned seems to focus on investigating the effects of replacing cement with rice husk ash and eggshell powder on the mechanical properties of concrete. By incorporating these waste materials into concrete mixtures, the study aims to reduce the environmental impact of construction activities, lower construction costs, and promote sustainable building practices.
