This study investigated the effects of using limestone powder and Shirasu natural pozzolan, as partial replacements for fine aggregate, on the mechanical properties and resistance of concrete to an aggressive solution containing 3% H2SO4 and 5% MgCl2. The data show that replacing 5% of the fine aggregate with limestone powder results in more severe deterioration of the concrete by the chemical solution. However, replacing 55% of the fine aggregate with Shirasu both increases compressive strength after a 28-day cure and improves chemical resistance of concrete. In addition, the deterioration mechanism of concrete immersed in the aggressive solution was examined in this study.
