Studying the Effect of Adding Sodium Silicate and Rock Wool to Concrete Mix on the Properties of Concrete

Abstract

This research is studying effect of adding sodium silicate to water of concrete mix with ratios (2.5%, 3.75%, 5% and 6.25%) by the weight of water concrete mix. Also study effect adding rock wool to concrete mix with ratios (2.5%, 3.75%, 5% and 6.25%) by the weight of cement. After demolding the samples and curing in water 28 days and then dried in air to be ready to test. The samples tested compressive strength and tensile strength and density, the results show increase in compressive strength and tensile strength in ratios (2.5% rock wool and 3.75% of sodium silicate) compared to reference sample, and the density of samples decrease by increase the ratios of additives rock wool and sodium silicate to concrete mix.
