Predictive Models for Determining Compressive Strength of Concrete with Marble Dust as a partial replacement of cement with the Application of ANN

This paper proposes an experimental study of the influence of waste marble dust used as supplementary cementitious material on the mechanical properties and durability of concrete Mix25. Marble is a metamorphic form of limestone (CaCO3). Waste marble dust has been elected as the replacement for cement for the reason of having high calcium oxide content present in marble dust. It uses marble dust as a partial replacement to accomplish sustainable concrete. That will be a sustainable move toward the environment by using waste dust segregated from the wastage of marble cutting. Second, the WMP has a specific gravity of 2.6 and the specific gravity of cement is 3.16, which helps to reduce the weight of concrete as much as we add up the marble dust. Based on previous studies, concrete mixes are prepared at the replacement percent of 10%, 20%, 30%, and 40%. The compressive strength of the concrete was evaluated with this partial replacement of cement with marble dust. Also, workability, fineness, consistency & the initial setting time test are performed. The analysis of the experimental result on concrete at 10%, 20%, 30%, 40% content of waste marble dust shows that it contributes to increase of the workability of concrete. On the contrary, it will reduce the strength of concrete as the quantity of marble dust increases
