摘要
为了研究掺聚丙烯纤维后C120钢筋混凝土梁的力学性能,对12根梁进行了抗弯试验。研究结果表明,聚丙烯纤维在现有掺量下对构件的抗裂性没有影响;两种配筋的构件随着聚丙烯纤维掺量的提高,其塑性变形阶段稍有延长,但对构件延性改善并不明显。
In order to study the mechanical behavior of C120 RC beam with addition of polypropylene fibres and bending tests of 12 such beams were carried out.It turned out that polypropylene fiber did not affect crack resistance of sample in the existing content.With the increases of polypropylene fiber content for two kinds of reinforcement concrete members,the plastic deformation stage was slightly extended,but the improvemant on ductility improvement was not obvious.
