Experimental study on properties of concrete using latex and rock wool fibre

Abstract

The research focuses on the use of styrene-butadiene rubber latex and rock wool fibre for the improvement of the mechanical properties of concrete and its effects on elevated temperature. Material properties play a most important part in the performance of concrete material during its lifetime. The Compressive strength of concrete at high temperature is most important in fire resistant design. Cement mortar cube is prepared with varying percentage of latex 0% to 10% by replacing the weight of water with the optimized ratio of mineral wool fibre from 0% to 0.50% to the volume of the mix. The final optimized percentage of styrene butadiene rubber latex and rock wool fibre is of 6% by the weight of water and 0.20% of the volume of mix. This optimized percentage is added to concrete and the variation of mechanical properties, residual compressive strength, mass loss at elevated temperature and water absorption tests are presented.
