Abstract

본 발명은 콘크리트 혼합물 내에 투입하여 콘크리트의 양생 과정에서 발생되는 수축력을 고르게 분산시킴으로써 콘크리트의 수축 균열을 방지하기 위한 콘크리트 보강용 이형단면 단섬유 및 그 제조 방법에 관한 것으로, 특히 섬유의 단면을 삼각형, 사각형 Y형 등으로 형성하고 이를 S방향 또는 반대 방향인 Z방향으로 꼬임을 주어 표면이 비틀려지게하여 절단한 다음 이들을 솜을 타듯 타면하여 고르게 혼합하고낱개의 단섬유로 풀어 해침으로써 콘크리트 혼합물 내에서 보강용 섬유가 미끄러져 빠지는 단점과 분산성을 개선한 것을 특징으로 하는 콘크리트 보강용 이형단면 단섬유 및 그 제조방법에 관한 것이다.The present invention relates to a single-sided single-fiber for reinforcing concrete to prevent shrinkage cracking of concrete by uniformly dispersing shrinkage force generated during the curing process of concrete by putting it in the concrete mixture, and in particular, the cross section of the fiber is triangular, It is formed into a square Y shape and twisted in the S direction or the Z direction opposite to the surface, and the surface is twisted and cut. It relates to a release cross-section short fiber for concrete reinforcement, and a method for manufacturing the same, characterized in that the reinforcing fiber slips out and improves dispersibility.
