Use of Waste Marble Powder as Partial Replacement in Cement Sand Mix

Abstract

As nowadays, marble is widely used in structures which increase the amount of waste that obtained from it. As marble powder is the waste product, obtained during the process of sawing and shaping of marble by marble rock, which contains heavy metals which make the water unfit for use. Marble powder creates environmental problems but due to a presence of high oxide calcium content, which is cementing property, marble can be used as in the partial replacement of cement in cement sand mix. In this study, we collect the waste marble powder from the industry and investigate its effects on the cement sand mix in different proportion and also compare the compressive, split tensile and flexure strength of cement sand mix. We also compare its workability and durability. The main objective of this study is to develop useful concrete mixes using waste marble powder as partial replacement of cement and sand.
