800℃ 조건에서의 시멘트 경화체의 균열 특성
Cracking Behavior of Cement and Concrete Damaged by High Temperature of 800℃

초록
In this study, the cracking characteristics of cured pastes at 800℃ were investigated by X-ray CT. The test specimens were fabricated with and without aggregate, and the heating rate condition was applied at rapid heating (10.0℃/min). It is considered that the rapid heating condition does not cause a temperature gradient phenomenon because the temperature difference between the surface and the center of the sample is small due to a low heating rate unlike an actual fire. The cracking condition of the specimens without aggregate was more severe than that of specimens with aggregate.
