INFLUENCE OF SLAG POWDER ON STRENGTH AND RESISTANCE TO SIMULATED ACID RAIN OF CEMENT MORTAR

The influence of slag powder on the fluidity,strength and resistance to simulated acid rain of cement mortar was analyzed.In the experiment conditions,the fluidity property and strength of cement mortar could be improved with the increase of slag powder mixture,and the compressive strength of the hardened cement mortar which cured in water with different slag powder contents could go up to the same value later in the experiment.The strength of cement mortar with the additive of slag powder was better than that of pure cement mortar after simulated acid rain(pH=4.0)corrosion.The addition of slag powder could improve the acid rain resistance of cement mortar.
