An Evaluation of Coarse Aggregate Mixed Effect on Impact Resistance of Fiber Reinforced Cement-Based Material

섬유보강 시멘트 기반 재료의 내충격 성능에 미치는 굵은 골재 혼입 영향 평가

In this study, it evaluate the coarse aggregate mixed effect to impact resistance performance of the fiber reinforced cement-based material. The type of fiber is Hooked-ended steel fiber, and mixed 1vol.% in concrete and cement composites. The impact experiment was conducted by using a spherical shape projectile diameter of 25mm to 170m/s speed and Impact resistance performance was evaluated by measuring the fracture grade, fracture diameter and depth.
