Abstract |
In this study, the mechanical, durability, and self-healing performance of mortars incorporating CMC, an cementitious materials-based capsule, were compared and analyzed. As a result of the analysis, the compressive strength at 56 days of age of the samples incorporating CMC was similar or relatively higher than that of the control sample, and the passing charge at 56 days of the B-FA sample was about 20.6 % lower than that of the control sample. In addition, the compressive strength recovery ratio of the samples incorporating CMC was superior to that of the control sample, and the compressive strength recovery ratio at 56 days of healing of the B-FF and FA-FS samples was the highest at about 126~127 %. In the case of healing ratio, the B-FF sample showed the highest healing ratio of about 81 %, which is about 38 % higher than the control sample.
