近年来,为进一步改善钢筋混凝土的物理力学性能,提高它们的强度,降低材料消耗和缩减建造劳动量;国外,纤维增强混凝土有着较大的发展,它是一种有前途的建筑材料。目前,采用和试验了各种增强纤维。就其材料性质可分为矿物材料如石棉、棚、碳素、玻璃纤维;合成材料如尼龙、聚酯、聚丙烯、芳香基聚酸胺等纤维; In recent years, in order to further improve the physical and mechanical properties of reinforced concrete, increase their strength, reduce material consumption and reduce the amount of construction labor; in foreign countries, fiber reinforced concrete has great development, it is a promising building material. At present, various reinforcing fibers have been used and tested. Its material properties can be divided into mineral materials such as asbestos, sheds, carbon, glass fiber; synthetic materials such as nylon, polyester, polypropylene, aromatic polyamide and other fibers;
