为了提高混凝土材料的拉压比,降低其脆性,使之得到更广泛的应用,人们试图寻求各种途径。目前,钢纤维增强混凝土是最有发展前途的一种方法。而在钢纤维混凝土中影响其增强效果的因素较多,其中钢纤维的配向性是主要的因素之一。本文就这个问题通过试验并在理论方面进行了探讨,定量地得出了钢纤维在混凝土中定向配向的不同增强效果,为进一步提高钢纤维的增强效果提供了理论依据。 In order to increase the tensile ratio of the concrete material and reduce its brittleness, it has been used more widely and people have sought various ways. At present, steel fiber reinforced concrete is one of the most promising methods. There are many factors affecting the reinforcing effect in steel fiber concrete, and the alignment of steel fibers is one of the main factors. In this paper, through experiments and theoretical discussions on this issue, different enhancement effects of orientation of steel fibers in concrete are quantitatively obtained, which provides a theoretical basis for further enhancing the reinforcing effect of steel fibers.
