摘要
在混凝土中掺用钢纤维,能显著提高混凝土的抗拉、抗弯、抗剪强度。将掺用波形和哑铃形的钢纤维混凝土与常规混凝土的力学性能进行了对比试验研究,其增强效果显著,而且随钢纤维性能形状不同增强效果不同。
Steel fiber mixed in concrete may obviously increase the tensile, bending and shearing strengths of the concrete. The mechanical properties of ordinary concrete are compared with concrete with wave-shaped and dumb-bell shaped steel fiber through tests. The test results show that the effect of steel fiber in improving concrete strength is obvious and differs with different shapes of the steel fiber.
