Assessing Effects of Fine Aggregate Size on the Mechanical Properties of HPFRCCs Reinforced with PVA Fiber

PVA 섬유로 보강된 고인성 시멘트 복합체의 역학적 특성에 대한 잔골재 치수의 영향 평가

HPFRCCs(High performance fiber reinforced cementitious composites) exhibit characteristics of strain harding and multiple crack. These lead to improvement in ductility, toughness, and deformation capacity under compressive and tensile stress. These properties of HPFRCCs are affected by type of fiber, size of sand. Furthermore these influence compress strength and flexural strength. Therefore experimental study on the mechanical properties of HPFRCCs using PVA fiber was carried out. In this paper, HPFRCCs made of PVA fiber were tested with size of sand, strength of concrete to evaluate characteristics of compressive strength and flexural strength.
