将长度为19mm聚丙烯纤维和长度为30mm钢纤维,按照不同掺量分别加入到C30混凝土中,以钢锤自由下落进行抗冲击试验。试验结果表明:聚丙烯纤维和钢纤维的加入对混凝土抗冲击性能的提高有良好的增强作用;高弹性模量增强纤维的增强效果优于低弹性模量纤维。
The length of 19mm polypropylene fiber and the length of 30mm steel fibers were added to the C30 concrete according to different dosage, with a free-falling steel hammer impact test. The experimental results show that the addition of polypropylene fiber and steel fiber can enhance the impact resistance of concrete effectively, and the enhancement of high elastic modulus fiber is better than that of low modulus fiber.
