나일론 섬유의 길이변화에 따른 섬유보강 바닥마감용 콘크리트의 공학적 특성

Engineering characteristics of the Fiber Reinforced Floor Finishing Concrete According to the changes of Nylon Fiber Length

This study investigated the fundamental properties corresponding to various length changes on NY fiber reinforced concrete. For results of fresh concrete, the slump and air content were declined, but the unit volume weight and vebe time were increased. For the hardened concrete properties, the compressive strength showed increasing tendency according to the NY fiber length. The dry and autogenous shrinkage also decreased compared with Plain. Generally, the caes that 19 mm NY fiber was used was better than any other cases.
