Abstract:
The experiment, which is to evaluate crack-filling efficiency by self-healing when cracks occur by the external impact and internal stress, was conducted in this study. The crack-filling can be achieved by silica sand, which was applied self-healing ingredient. Therefore, recovery of crack was evaluated because it was verified feasible of silica sand, which was applied self-healing ingredient. As a result, when self-healing ingredient of silica sand surface reacts with water, it was verified that recovery of crack was achieved silica sand, which was applied self-healing ingredient. Based on the results, it may be applied construction structure after various durability tests and analysis. Also, the repair mortar may be applied.
