Evaluation of Strength Characteristics of Concrete Using Marble Sludge Powder

Abstract

Concrete is a construction material consisting of cementitious material, fine aggregate, coarse aggregate and water. Now a days the cost of these materials are increased so, we need to look at a way to reduce the cost of building materials especially cement. One of the recent advancement in construction industry is replacement of materials in concrete. The replacement of materials offers cost reduction, energy savings and protection of environment. To achieve the above objective we are partially replacing the cement with marble sludge powder (MSP) produced from marble industries. The current study aims to investigate the fresh and hardened properties of concrete when cement is replaced in part by marble sludge powder. The work is centered on the M40 concrete grade. In this study, the percentages of marble sludge powder that replaced cement were 0%, 5%, 10%, 15%, and 20%. The fresh properties are workability and hardened properties are compressive strength at 7, 28, days of curing, split tensile strength, and flexural strength of concrete are to be determined. The results show that replacing 10% to 15% of the cement with marble sludge powder improves the workability, compressive strength, flexural, and split tensile strengths of concrete.
