喷射纤维混凝土是将喷射混凝土和纤维混凝土的优良特性结合在一起,是一种新型复合材料和施工办法,在灾后或其他原因破损建筑加固和修复中,以其特殊的材性、有优良的力学性能、可靠的安全度,越来越受到工程界的重视。我们对其试验设计部分进行一些探讨和研究,得出掺入聚丙烯纤维喷射混凝土提高了传统喷射混凝土抗拉、抗折、抗弯强度,增加了混凝土的密实性、耐久性。
Sprayed fiber concrete is the combination of the excellent properties of shotcrete and fiber concrete. It is a new type of composite material and construction method. In the post-disaster or other causes of damage to the building reinforcement and repair, with its special material, excellent mechanical Performance, reliable safety, more and more attention by the engineering community. In this paper, we make some research and research on the experimental design. It is concluded that the incorporation of polypropylene fiber sprayed concrete improves the tensile, flexural and flexural strength of traditional shotcrete, and increases the compactness and durability of concrete.
