초록
This study is conducted to investigate the characteristics of cracks depending on the different mixture rates of calcium hydroxide and distilled water in high-strength concrete, which is substituted with a high percentage of blast-furnace slag, by using specimens produced under different heating temperatures: 600℃, 800℃, and 1000℃, respectively. According to the results of the study, the specimen heated under the temperature of 600℃ did not produce cracks; the specimen heated under 800℃ produced little cracks and showed no difference between calcium hydroxide and distilled water; whereas the specimen heated under 1000℃ produced cracks larger than 5mm on average in the case of calcium hydroxide, compared to distilled water.
