钢纤维外形对其增强性能的影响

摘要

According to the comparison on two kinds different types steel fiber enhancing cement mortar, the paper finds out that the bond strength of spiral type steel fiber and matrix is obviously higher than straight type steel fiber, thus getting the conclusion that the shape of the steel fiber has non-negligible significance in steel fiber enhancing concrete, and providing experiment basis for application of the spiral type steel fiber.%通过对比两种不同类型的钢纤维增强水泥砂浆,发现螺旋型钢纤维与基体的粘结强度要明显高于平直型钢纤维,从而得出钢纤维外形在钢纤维增强混凝土中具有不可忽略的意义,同时也为螺旋型钢纤维的应用提供了实验依据.
