本文介绍通过在钢纤维两端弯钩的方法提高钢纤维与混凝土之间的握裹力。经优选获得的 K—5型高碳钢丝弯钩纤维配制的混凝土与用平直钢纤维配制的混凝土相比,在抗弯强度相同的条件下,钢纤维用量可减少三分之二。
This article describes how to improve the bond between the steel fiber and the concrete by hooking the two ends of the steel fiber. The preferred K-5 type high-carbon steel wire hooking fibers prepared concrete can reduce the amount of steel fiber by two-thirds under the same bending strength as the concrete prepared with flat steel fibers.
