초록

본 연구는 화재피해를 입은 섬유혼입 고강도 콘크리트를 대상으로 표면처리제를 적용한 뒤 표면처리제의 종류에 따른 중성화 깊이를 비교 평가하였다. 실험 결과 표면처리제의 종류에 따른 중성화 저항성는 폴리머계 표면도포제, 규산리튬계 표면함침제, 규산나트륨계 함침제 순으로 우수한 것을 확인하였다.

영어초록

In this study, the carbonation depth according to the type of surface treatment materials was evaluated by applying the surface treatment method to the fire damaged fiber-reinforced high-strength concrete. As a result of the study, it was confirmed that the carbonation resistance according to the type of surface treatment materials was superior in the order of a polymer coating, lithium silicate impregnation, and sodium silicate impregnation. In addition, in the case of polymer coating, it was confirmed that the carbonation did not proceed significantly due to accelerated carbonation even if scratches of 0.5mm or less, which may occur during the use of building after construction.
