- bundle-type short fibers for fiber reinforced concrete using p-aramid conjugate fiber and fiber Reinforced concrete using thereof
The present invention relates to a bundle-type short fiber (1) for reinforcing concrete for increasing compressive strength and flexural tensile strength by being added to a concrete composition to enhance interfacial adhesion, flowability and dispersibility. The bundle-type short fiber (1) for reinforcing concrete is manufactured by twisting para-aramid composite fibers through a twisting process or covering process, heat-treating the fibers through a resin impregnation process, and then cutting the same. Further, the present invention relates to a fiber reinforced concrete composition in which the bundle-type short fiber (1) for reinforcing concrete is mixed to enhance compressive strength and flexural tensile strength.
본 발명은 콘크리트 조성물에 첨가되어 계면접착력과 흐름성 및 분산성이 개선함으로서, 압축강도 및 휨인장강도를 증대시키기 위한 콘크리트 보강용 번들(bundle)형 단섬유(1)에 관한 것이다. 상기 콘크리트 보강용 번들(bundle)형 단섬유(1)는 파라-아라미드 복합섬유를 연사공정 또는 커버링공정을 통해 꼬임을 부여하고, 수지함침공정을 거쳐 열처리한 후 절단하여 제조된다. 또한 본 발명은 상기 콘크리트 보강용 번들(bundle)형 단섬유(1)가 혼입되어 압축강도와 휨인장강도가 개선된 섬유보강 콘크리트 조성물에 관한 것이다.
