매크로 합성 섬유가 혼입된 초기 재령 콘크리트의 역학적 특성에 관한 실험적 연구

Abstract

The purpose of this study is to investigate the mechanical properties of concrete containing polypropylene macro-synthetic fibers rather than conventional micro-synthetic fibers. Macro-synthetic fibers are less active in hairball than micro-synthetic fibers, and they are widely used in slabs and road pavements in the United States because of their high workability and improved crack resistance. To evaluate the material performance, compressive strength and fiber content were set as variables and physical performance was reviewed by age. The compressive strength, splitting tensile strength and flexural tensile strength test was carried out. As a result, the stress-strain variation by age was observed according to compressive strength and fiber content.
