PARTIAL REPLACEMENT OF CEMENT WITH MARBLE POWDER IN CONCRETE: EFFECT ON STRENGTH AND SORPTIVITY

ABSTRACT

This research project, entitled "Experimental Study on the Effect of the Partial Replacement of Cement with Marble Powder on the Compressive Strength and Sorptivity of Concrete" aims to delve into the impact of partially replacing conventional cement with marble powder (MBP) on concrete's compressive strength and sorptivity. As sustainability becomes a paramount concern in the construction industry, exploring alternatives and incorporating waste materials is of increasing importance. The study involves the preparation and testing of various concrete mixtures with varying percentages of marble powder (MBP) replacement for cement. The outcomes are expected to shed light on the feasibility and potential advantages of using marble powder (MBP) as a partial substitute for cement in concrete. This study directly addresses this imperative by investigating the practicality of integrating marble powder (MBP) as a partial replacement for cement in concrete. Marble powder (MBP), a byproduct of the stone industry, not only contributes to waste reduction but also presents economic and environmental benefits. Through a series of experiments involving different percentages of marble powder (MBP) replacement (0%, 2%, 4%, 6%, 8%, and 10%), we evaluated the compressive strength and sorptivity of the resulting concrete specimens to understand how marble powder (MBP) content influences these crucial properties. According to this research, the results showed that as the percentage of marble powder concrete increases, the compressive strength decreases alongside its cost and the weight of concrete. At around 10% partial replacement of coarse aggregate with marble powder in concrete gives a significant decrease in cost and weight of the concrete without much affecting the compressive strength of concrete
