Effects of Zeolite and Used Foundry Sand in Concrete

Abstract

In Current scenario, the CO2 concentration is getting increased in the environment which leads to climatic change and greenhouse effect. By using zeolite powder (pozzolanic material),it can reduce the CO2 emissions in the atmosphere. Using zeolite as partial replacement material of cement could make the concrete high strength, hence it eco-friendly. Used Foundry Sand (UFS) is an industrial by-product which is another material used in this research. The UFS can be used as a replacement for natural sand due to its properties.The present research work is aimed at studying the effect of the physical and chemical properties of Zeolite and UFS in M20 grade concrete. Based on previous literature 10, 15 and 20 % of Zeolite as replacement of cement and 30 % of UFS as replacement of sand are considered for the present study. The main objective is to estimate the test result of using Zeolite and UFS as partial replacement for cement and fine aggregates in fresh and hardened properties of concrete. Compressive strength and split tensile strength were carried out for 7,14 and 28 days and flexural strength of element will be observed from optimum percentage of test result.
