Outdoor Exposure Test of Concrete Containing Supplementary Cementitious Materials

Abstract:

An outdoor exposure test was conducted to investigate the resistances of concrete containing supplementary cementitious materials (SCMs) to carbonation and chloride ingress at three outdoor exposure testing sites in Japan. The test results indicated that concrete specimens containing larger amounts of SCMs exhibited larger carbonation depths but the carbonation rates decreased as the testing period was extended. Additionally, the resistance to chloride ingress was improved by the use of SCMs in cases where the carbonation depths were negligible. Concrete specimens containing high-volume SCMs, however, showed inverse chloride profiles due to large carbonation depths; chloride contents were low in zones of carbonation but large beyond these zones. The resistance to carbonation was found crucial for preventing reinforcement corrosion induced by not only carbonation but also incidental chloride ingress in concrete containing high-volume SCMs.
