Research for Performance Evaluation of Crack Reduction in Fiver Reinforced Concrete with Jutes

황마 섬유를 이용한 섬유 보강 콘크리트의 균열 저감 성능 평가에 관한 연구

In this study, three kinds of cellulose fibers to crack reduction performance were evaluated and the results are as follows. Plastic shrinkage cracking is evaluated by the relative crack area, at all levels between $0.9kg/m^3$ and $1.2kg/m^3$, except for UF0.9% of upto50% showed are duction compared with Plain. In according to recommended amount of fiber in each area of the crack HF0.9>CEL1.2>UF0.6 effect of the order was more effective. While the impact strength of UF and CEL fibers until the final destruction are about five times the number of falls, HF fiber count drop was 10-18 time.
