Influence of Barite Sand on The Strength on Self-Compacting Concrete with Fly Ash

Abstract

This study compared the performance of self-compacting concrete (SCC) based on fly ash addition and limestone filler. A SCC prepared with Portland cement, river sand, and limestone filler was used as a reference sample. Additional experimental self-compacting concretes with different types of fine aggregates, fillers, and special additives for increasing freeze-thaw resistance were prepared and optimized. The correlation between mix design, i.e., percentage of barite sand and additives, on properties of hardened SCC (compressive and flexural strengths), were investigated and discussed.
