Marble is widely used in structures, it increases the amount of waste powder obtained. As marble powder is a waste product obtained during the process of sawing and shaping of marble by marble rocks which contains heavy metals that makes the water unfit for use. Since marble powder has cementing property it can be used in concrete as partial replacement of cement. In this study, waste marble powder has been collected from the industry and its effect on the concrete mix has been investigated by incorporating marble dust as partial replacement of cement as 10%, 15% and 20%. Steel fibres in different proportion such as 0%, 0.5% and 1% were added by volume of concrete. Mechanical properties such as compressive strength, splitting tensile strength and flexural strength were determined for all the combinations of marble powder and steel fibre. Durability properties such as drying shrinkage and sorptivity were determined and the obtained results were compared with control concrete. Further, using Taguchi based grey relational analysis optimisation of marble powder and steel fibre was carried out. © 2019 Associated Cement Companies Ltd.. All rights reserved.
