【Abstract】 Ultrasonic inspection and compressive strength of 240 sets of the steel fiber reinforced concrete test pieces were investigated experimentally.According to the regression analysis of the test results,the authors set up a test curve of the ultrasonic velocity and the compressive strength.Based on this curve,the compressive strength of steel fiber reinforced concrete can be obtained by its ultrasonic velocity.The application of the ultrasonic technology in steel fiber reinforced concrete non-destructive inspection is suitable and feasible.更多还原
