Abstract

The purpose of this study is to investigate experimentally the compressive strength and tensile behavior of cement composites reinforced by selvedge short fiber from high performance fabric. Four types of mixtures according to the types of selvedge short fibers were prepared and compressive strength and tension tests were performed. Test results showed that the compressive strength values of composites investigated in this study ranged from 64 MPa to 66 MPa and all composites showed strain-hardening behavior. The tensile strain capacity values of composites ranged from 2.6 % to 2.8 % and multiple cracking behavior was observed in all composites.

이 연구의 목적은 고성능 원단의 셀비지 단섬유를 적용한 섬유보강 시멘트계 복합재료의 압축강도와 인장거동 특성을 실험적으로 조사하는 것이다. 이를 위하여 셀비지 단섬유 종류에 따라 4종류의 배합을 준비하였고, 압축강도 및 인장 실험을 수행하였다. 실험결과 압축강도는 64 MPa에서 66 MPa 범위로 고강도를 나타내었으며, 모든 배합에서 변형경화 현상이 나타났다. 인장변형성능은 2.6 %에서 2.8 %로 고연성이 나타났으며, 다중균열이 관찰되었다.
