1 概述 1 overview 钢纤维混凝土的应用起始于20世纪60年代。由于纤维的形状、施工技术的提高和改进,从70年代起,钢纤维混凝土成为商品并得到应用,其使用范围也在不断扩展。 The use of steel fiber concrete began in the 1960s. Due to the shape of the fiber, the improvement of construction technology and improvement, since the 70 s, the steel fiber reinforced concrete as goods and get the application, the scope of its use is also growing. 钢纤维混凝土是用一定量乱向分布的钢纤维增强的以水泥为粘结料的混凝土,属于一种新型的复合材料。由于其抗裂性特强、韧性很大、抗冲击与耐疲劳强度高、抗拉与抗弯强度高,广泛应用于道路、机场、桥梁、水工、港口、铁路、矿山、隧道、军事及工民建等工程领域。 Steel fiber concrete is a kind of new composite material which is reinforced by a certain amount of the steel fibers that are distributed. Due to its crack resistance strong, toughness big, impact resistant and high fatigue strength, tensile and bending strength is high, widely used in roads, airports, Bridges, water, ports, railways, mines, tunnels, such as military and civil engineering field. 钢纤维喷射混凝土是通过管道输送装置在高压作用下将掺入钢纤维的混凝土拌合物高速喷射到施工作业面的的一项技术。[1] Steel fiber reinforced shotcrete is a device through the tubes under the effect of high pressure will be added to the steel fiber concrete mixture of high-speed jet to the construction of the operation of a technology. [1] 钢纤维喷射混凝土首次于1973年在美国爱华达州得到应用,其后,将其成功应用于隧道衬砌、斜坡稳定、涵洞、水库等其他结构工程。 Steel fiber reinforced shotcrete in the United States in 1973 for the first time love has been applied Nevada, followed by its successful application in tunnel lining, slope stability, culverts, reservoir engineering and other structures.
