钢纤维混凝土是一种新型的复合材料,它是将短而细的钢纤维均匀地分散在混凝土或砂浆中,从而显著地提高混凝土的抗裂性和抗拉强度。从七十年代起,国际上对钢纤维混凝土引起了广泛的重视,主要表现在三个方面:1.在试验研究的基础上探讨非连续的不定向配筋体的工作机理,这是当代公认的难题之一;2.钢纤维加工方法的改进使价格急剧下降,且有成品出售,故在商业上和技术上更具有竞争力;3.现场施工工艺的研究和发展,使它能日益广泛地应用于军事工程和土木工程、公路桥梁以及水利工程等各个领域。
Steel fiber reinforced concrete is a new type of composite material, which disperses short and thin steel fibers uniformly into concrete or mortar to significantly improve the crack resistance and tensile strength of concrete. Since the seventies, the international community has aroused extensive attention to steel fiber reinforced concrete, mainly in three aspects: 1. On the basis of experimental research to explore the working mechanism of non-continuous non-oriented reinforcement body, which is currently recognized One of the problems; 2 steel fiber processing methods to improve the sharp decline in prices, and there are finished products sold, it is commercially and technically more competitive; 3 on-site construction technology research and development to make it increasingly widespread Used in military and civil engineering, highway bridges and water conservancy projects in various fields.
