본 연구에서는 FRC의 성능향상과 소성수축으로 인하여 발생하는 균열을 저감할 목적으로 NY 섬유를 사용한 콘크리트의 제반공학적 특성을 실무 현장에서 많이 보급되어 사용되고 있는 셀룰로오스 섬유(Cellulose fiber : 이하 CEL) 콘크리트와 상호 비교하여 그 특성에 대하여 분석하고자 한다. |

This study is to investigate the effects of nylon(NY) and cellulose(CEL) fiber contents on the mechanical properties of the concrete. The results were summarized as following. Test showed that increase of NY and CEL fiber contents decreased fluidity of fresh concrete,so the loss of the fluidity would be considered when they were over added. Air contents were slight increased,bu t they satisfied the target air content. Bleeding capacity of concrete containing fiber significantly was declined. In addition,c oncrete containing higher amounts of fiber retarded setting time remarkably. Plastic shrinkage crack was reduced with the use of fiber due to increasing fiber contents and changing fiber classes,an d NY fibers to prevent the plastic shrinkage crack effectively. Compressive and tensile strength of almost specimens were increased when air contents of the fresh concrete were fixed according to fiber contents,an d flexural strength was increased according to fiber contents. For the impact strength of specimens, the specimen containing 0.6kg/㎥ of NY fibers,show ed the most favorable impact strength,The fiber reinforced concrete using NY fibers exhibited superior mechanical performance,an d it was considered that 0.6kg/㎥ was desirable as the most favorable adding amount. |
