Properties of self-compacting concrete developed using marble dust as a partial replacement of fine aggregates

Abstract

This study looked into the possibility of substituting marble dust for some of the fine aggregates used in concrete production. The purpose was to determine if such a substitute may improve concrete’s properties while also minimizing the negative consequences of mining and processing natural sand and assisting in the attainment of sustainability goals. Experimental testing was done on a variety of concrete mixtures that contained various amounts of sand and marble dust. Compressive strength, flexural strength, and workability were evaluated for a control mix consisting entirely of unrefined sand. The results showed that there was little difference in concrete’s compressive or flexural strength when up to 30% marble dust was used in place of sand. The workability and strength, on the other hand, decreased as marble dust concentrations rose. contains marble dust.
