钢纤维混凝土是由直径为0.25～0.76mm、长6.4～76mm的钢纤维、水泥,细、粗骨料组成的一种新型复合材料。虽然钢纤维混凝土研究、生产、应用的历史还不长,但已经以良好的性能和广泛的用途,引起工程界的关注。一、钢纤维混凝土发展情况有关钢纤维混凝土的最早文献见之于本世纪初。美国Porter于1911年提出在混凝土中均匀掺入钢纤维,作为增强材料的建议。其设想与现在的钢纤维混凝土大体相同。1911年,美国Graham通过研究搞清了在普通钢筋混凝土中掺入钢纤维后,强度
Steel fiber reinforced concrete is a new kind of composite material composed of steel fiber, cement, fine and coarse aggregate with a diameter of 0.25-0.76mm and a length of 6.4-76mm. Although the history of research, production, and application of steel fiber reinforced concrete is not long, it has attracted the attention of the engineering community with its good performance and wide application. First, the development of steel fiber reinforced concrete The earliest document on steel fiber reinforced concrete was seen in the beginning of this century. In 1911, Porter of the United States proposed to uniformly incorporate steel fibers in concrete as a reinforcement material. Its idea is almost the same as the current steel fiber concrete. In 1911, Graham of the United States made a study to find out the strength of ordinary steel reinforced concrete after incorporation of steel fiber.
