Abstract

Initial crack in concrete structure is mentioned as a factor which lower durability. Then, the purpose is an index of a crack test in the ability test type. In this study, three point bending test of mortar with a crack initiated was carried out, and strength was examined. The factor was the type of cement, the time of crack initiated, and the curing period. The system of the strength recovery is the hydration of the unhydrated cement at the initial crack
