要旨 This study investigated the deterioration of concretes caused by the attack of an aggressive chemical solution composed of 3% sulfuric acid and 5% magnesium chloride. A part of fine aggregate was replaced with Shirasu natural pozzolan and/or limestone powder. The results showed that after 12 weeks of immersion, the compressive strength loss, neutralization depth and chloride penetration depth of concrete containing Shirasu were lower than those of concrete without Shirasu. The addition of limestone powder can result in more severe deterioration of concrete.
