Abstract

In this study, the changes of the expansion and strength according to the temperature of the emergency repairing expansion material were examined by cup foaming test and uniaxial compressive strength test, and the accelerated compression creep test was carried out to confirm the long term stability. Ramp & Hold test and accelerated compressive creep test were performed to evaluate the creep performance. The short - term creep test was used to determine the initial creep strain of the expanding material. The isothermal method using time - To evaluate the long - term compressive creep performance.

본 연구에서는 긴급복구용 팽창재료의 온도에 따른 팽창량 및 강도의 변화를 컵발포 실험과 일축압축강도 실험을 통하여 물리적 특성을 확인하였고, 장기안전성을 확인하기 위하여 가속 압축 크리프 시험을 진행하였다. 크리프 성능을 평가하기 위하여 단기 크리프 시험과 가속 압축 크리프 실험을 실시하였으며, 단기크리프 실험은 팽창재료의 초기 크리프 변형률을 결정하고 시간-온도 중첩정리가 적용된 단계 등온법은 가속시험방법으로 장기 압축 크리프 성능을 평가하였다.
