Experimental study of partial replacement of cement by waste marble powder in a concrete prepared with artificial sand

Abstract

Marble is the most common building material having a huge amount of waste. This waste causes dust pollution also it makes soil infertile etc. Day by day marble waste goes on increasing. Another problem is regarding no availability of natural sand as resources of natural sand exhausting very rapidly also it contains a lot of deleterious materials to overcome this issue we can make partial replacement of cement by waste marble powder and natural sand by artificial sand. The concrete is made with heterogeneous material therefore compressive strength of concrete depends upon various materials with various trials. so the process is simplified in a mathematical technique called the regression method, which gives predicted compressive strength, if we get regression equation, it reduces the trials of concrete mix.
