Abstract

The purpose of this study is to investigate the compressive and tensile properties of high volume slag cement-based fiber-reinforced composite incorporating phase change material. Four mixtures were determined according to calcium hydroxide and expansive admixture, and the compressive strength and tension tests were performed. Test results showed that four mixtures showed a compressive strength over 51MPa and a tensile ductility over 3.2%. It was observed that calcium hydroxide and expansive admixture influenced the compressive and tensile performance, and the strength, ductility, and cracking patterns of composite could be improved by including proper amount of calcium hydroxide and expansive admixture.

이 연구의 목적은 상변화물질을 혼입한 슬래그 다량 치환 시멘트 기반 섬유보강 복합재료의 압축 및 인장성능을 실험적으로 조사하는 것이다. 이를 위하여 활성화제인 수산화칼슘과 팽창제의 양에 따라 4가지 배합을 결정하였고, 밀도, 압축강도 및 인장성능을 평가하였다. 실험결과 4가지 배합 모두 51MPa 이상의 압축강도와 3.2% 이상의 인장연성이 나타났다. 수산화칼슘과 팽창제는 압축 및 인장성능 영향을 미치는 것으로 나타났으며, 적절한 혼합을 통하여 강도, 연성, 균열패턴을 향상시킬 수 있는 것으로 나타났다.
