利用超声测试技术,进行了8组共计48个普通砼及钢纤维砼试件的力学性能试验.通过对试件裂缝的出现、发展及试件破坏过程的测试,获得了超声波在普通砼和钢纤维砼中传播的各种声学参数利用所测得的超声波穿过砼试件的传播时间及首波振幅衰减量,分析讨论了砼强度和钢纤维含量对声学参数的影响,并在此基础上对普通砼及钢纤维砼的力学性能进行了综合分析.结果表明,钢纤维砼的抗裂、抗拉等力学性能明显优于普通砼

Using ultrasonic testing technology, the mechanical properties of 8 groups of 48 ordinary concrete and steel fiber concrete specimens were tested. Through the test of the occurrence and development of cracks in the specimen and the failure process of the specimen, various acoustic parameters of ultrasonic propagation in ordinary concrete and steel fiber concrete were obtained, and the propagation time and first wave amplitude attenuation of ultrasonic waves through the concrete specimen were obtained, and the influence of concrete strength and steel fiber content on acoustic parameters was analyzed and discussed, and the mechanical properties of ordinary concrete and steel fiber concrete were comprehensively analyzed on this basis. The results show that the mechanical properties of steel fiber concrete such as crack resistance and tensile resistance are significantly better than ordinary concrete
