Abstract
This study aims to evaluate the resistance to seawater attack of mortars and concretes incorporating limestone powder (0, 10, 20 and 30% of cement by mass). In order to achieve this goal, both chemical resistance by seawater and chloride ions penetration resistance of mortars or concretes were regularly monitored. From the test results, it was observed that the durability of cement matrix was greatly dependent on the replacement ratios of limestone powder. In other words, performance of cement matrix with 10% limestone powder was similar to that of OPC matrix. However, it was found that a high replacement ratio of limestone powder was ineffective to resist seawater attack.
