The Establishment of Ultrasonic-Rebound Curve in Steel Fiber Concrete

Abstract:

For the application into country point highway of Xiamen to Kunming, a series of the C40 concrete with fly ash and slag have been studied by ultrasonic detection 、rebound detection and compression strength, analyzed the influence of ultrasonic velocity 、rebound value and compression strength with steel fiber content, fly ash and slag, the ultrasonic strength detecting wave of ultrasonic velocity、rebound value and compression strength is set up by regression analysis of the experimental data. The results show that the compression strength 、ultrasonic velocity and rebound value have good relativity, this ultrasonic-rebound detection method used in steel fiber concrete is simple and practical.
