초록

In this study, the performance of the self-healing with the granulated alkali activator (Ca(OH)2) manufactured in seawater environment is investigated for crack healing under 300 μm of cracks. Specimens combined with GGBFS and OPC with and without the granulated alkali activator were manufactured and immersed in seawater. After that, crack recovery on the surface of the specimens with the granulated alkali activator (Ca(OH)2) was also evaluated by the ultrasonic pulse velocity test. From the results, it was verified that cementitious materials with the granulated alkali activator, exposed in marine environments, could be able to heal or seal inside cracks
