摘要
采用不同几何尺度混杂钢纤维增强水泥基材料的断裂性能,结果表明,在纤维体积分数一定的情况下,几何混杂钢纤维对水泥基材料强度和断裂韧性的改善优于单一尺度钢纤维。选用适当混杂比的几何混杂钢纤维增强水泥基体,可制备出断裂性能较好的GHFRCC材料。
The fracture properties of geometrical hybrid steel fiber reinforced cement composites （GHFRCC） are investigated. With a constant fiber volume fraction, the geometrical hybrid steel fiber may increase the intensity and fracture malleability of cement composites more than mono - diameter fiber. Thus, once the hybrid ratio of two different diameter fibers is tailored properly, GHFRCC materials with superior fracture properties can be prepared.
