A STUDY ON PROPERTIES OF CONCRETE BY REPLACING CEMENT WITH MARBLE POWDER AND FLY ASH

Abstract

In this study, marble powder and fly ash are replaced with cement. Since Marble powder and Fly ash is a developing composite material that will allow the concrete industry to optimize usage of material, generate economic benefits and built structures that will be strong, durable, and sensitive to environment. Marble powder is a byproduct obtained during quarrying process of parent marble rock. The potential use of marble powder can be ideal choice for substituting in a cementitious binder due to presence of high calcium oxide content of more than 50%. Fly ash is another major byproduct of thermal power plant after combustion of coal at high temperature. Dumping these waste materials to the environment directly can cause serious environmental problems. So, using these materials in an economic way is recommended. In this project test results were obtained for M30 by replacing cement with marble powder at 0%, 5%, 10%, 15%, and 20% by volume has been made. The results were also determined by keeping fly ash constant at 10% which was accepted by Indian Standard and marble powder content was increased by 0%, 5%, 10%, and 15% All specimens were cured for 7,14, and 28 days before performing the lab tests such as compressive strength test and split tensile test. Further, the optimistic percentage of marble powder and fly ash was also determined
