EFFECT OF MARBLE POWDER AND STONE DUST BY PARTIAL REPLACEMENT OF CEMENT AND FINE AGGREGATE OF M-40 GRADE CONCRETE

Abstract

The waste powder was generated at every year millions of tons from industrial stone plants. It’s very serious damage to the environmental pollution. In that one of the stone plants is marble, it is used for decorative purposes in construction. During the process of marble cutting pieces some waste powder was released by plant. The waste marble powder was used in concrete construction by partial replace of cement. In this present study the concrete mix was prepared according to IS: 10262:2009 and the experimental studies we carried out to investigate the strength properties on M-40 grade concrete made with various mixes. In this study we include compressive strength, split tensile strength and flexural strength of hardened concrete. The materials which we are using are marble powder and stone dust as a replacement for cement and fine aggregate respectively. The percentage of cement replaced with marble powder is 10%, 20% and 30% along with replacement of fine aggregate with stone dust is 50%, 70% and 100% and the strength were compared with conventional concrete. In this study the set of cubes, cylinders and beams were casted for compressive strength, splint tensile strength and flexural strength respectively. The concrete specimens were tested after 7 days and 28 days after curing
