钢纤维混凝土是在混凝土中掺入钢纤维而改善性能的复合材料。它具有普通钢筋混凝土所没有的许多优良品质:如抗拉强度、抗弯强度、抗裂强度、韧性或抗冲击性能都可获得改善。 Steel fiber reinforced concrete is mixed with steel fiber in concrete and improve the performance of composite materials. It has a lot of ordinary reinforced concrete have no good quality, such as tensile strength, bending strength and crack resistance strength, toughness and shock resistance can be improve. 混凝土的缺点之一是抗拉强度甚小,仅为1.5~3.0MPa,而钢材则可达到400~1000MPa;混凝土的第二个缺点是抗拉断裂应变值很小,在10-4间,而钢材则在10-1间;混凝土的第三个缺点是因以上两个缺点的结果,及混凝土呈脆性,能量吸收小,抗冲击性能差,易发生裂缝。由于混凝土本质上的缺陷,使混凝土这种廉价材料在某些领域应用受液压钢坝  到限制。钢纤维的出现使混凝土的这些缺陷得到大大改善,也使混凝土的某些性能指标改变数倍之多。 One disadvantage of concrete is the tensile strength is very small, only 1.5 ~ 3.0 MPa, while steel can reach 400 ~ 1000 MPa; A second drawback of a concrete is tensile strain value is very small, between 10-4, while steel between 10-1; Concrete of the third disadvantage is that because of the drawback of the above two results, and the concrete is brittle, small energy absorption, shock resistance is poor, prone to fracture. Due to the defects of concrete in nature, makes concrete the cheap material application in some fields is restricted. The defects of the appearance of the steel fiber reinforced concrete have been improved greatly, and makes concrete some performance index change several times as much.
