ACCELERATED SULFATE ATTACK ON CONCRETE IN A HOT CLIMATE

This paper describes an accelerated experimental investigation to determine the effect of high sulfate concentration on concrete compressive strength. Concrete specimens were immersed in a 10 percent magnesium-sulfate solution to evaluate the effect of sulfate exposure on concrete compressive strength. The variable parameters were the type of cement, mixture proportions, curing period, and period of sulfate attack. Test results revealed that the water-content ratio had a significant impact on compressive strength after 15 months of sulfate exposure. Conclusions and recommendations for concrete mixes in hot climates are provided.
