- Abstract
- The object of this study is to develop the strength behavior of mortar under low-temperature(4℃~10℃). For this, with carrying out paste experiments, cure a paste as a fixed temperature of -10℃ base a classified mineral content that can be hardened at low temperature. then investigate a temperature record and specific strength. And, normal mortar possessing the W/C ratio 0.45 and repair mortars were cured at each primary factor variation of three classified curing stage, which are initial curing(20℃ standard sealed curing), main curing(low temperature(-10℃) sealed curing) and subsequent curing(4℃ sealed curing). Hence, the strength develop and freezing resistance of mortar were investigated and analyzed comparing the compressive strength and physical properties of cured mortar at the age of one and three days with those of the standard cured mortar. For micro structure analysis, we took some pictures of micro structure by SEM & TG/DTA in each type of curing temperature at same age.
