钢纤维指的是以切断细钢丝法、冷轧带钢剪切、钢锭铣削或钢水快速冷凝法制成长径比（纤维长度与其直径的比值,当纤维截面为非圆形时,选用换算等效截面圆面积的直径）为30～100的纤维。波纹钢纤维是钢纤维中应用比较广的一种。
Steel
fiber refers to fibers with a growth to diameter ratio (the ratio of
fiber length to diameter, when the fiber section is non circular, the
diameter converted to the equivalent cross-sectional area) of 30-100
using the methods of cutting fine steel wires, cutting cold rolled strip
steel, milling steel ingots, or rapid condensation of molten steel.
Corrugated steel fiber is a widely used type of steel fiber.
钢纤维具有****的延展性,耐磨损,硬度强,质料韧性较高,它的特征就是布局小,但方案有多种布局,搬家改动、歪曲、三角型、带锚尾等。钢纤维首要意图祇是为了与混凝土中之水泥、砂、碎石结合算了,而有好的结合就有好的成果及效能。钢纤维作为一种功能精良的新式复合材料出现在人们眼前,并得到了广泛的运用。运用钢纤维可以大约减小因荷载在基体混凝土引起的细缝隙端部的应力会集,然后控制混凝土缝隙的扩展,前进整个复合材料的抗裂性。
Steel
fiber has * * * * ductility, wear resistance, strong hardness, and high
material toughness. Its characteristic is that it has a small layout,
but there are multiple layouts available, such as moving modifications,
distortions, triangular shapes, and anchor tails. The primary intention
of steel fiber is only to combine well with cement, sand, and crushed
stone in concrete, and a good combination leads to good results and
effectiveness. Steel fiber has emerged as a new type of composite
material with excellent functions and has been widely used. The use of
steel fibers can approximately reduce the stress concentration at the
end of the fine gap caused by load on the matrix concrete, and then
control the expansion of the concrete gap to improve the crack
resistance of the entire composite material.
