Characteristics of the Strength and Toughness of Polypropylene Fiber Reinforced Concrete using Recycled Aggregates.

재생골재를 이용한 폴리프로필렌 섬유보강콘크리트의 강도 및 휨인성 특성연구

This study was performed to verify the properties of concrete used recycled aggregate(0, 30%, 50%). Also, to improve the brittle fracture, energy absorption and apparent ductility of concrete, we added polypropylene fibers(0, 0.1, 0.2, 0.5, 1.0% by volume of concrete). As the experimental results, adding 30% recycled aggregates and 0.5% polypropylene fibers to concrete mixes enhances the properties of both compressive strength and toughness.
