Ultrasonic Non-Destruction Detecting Method for Concrete Compression Strength

Abstract:

Regional materials and mixing ratio of Datong area are used to make the concrete testing blocks. The rebounding and ultrasonic non-destruction detecting testing for concrete strength were done by using the six types of strength grades concrete standard specimens according to the technical regulation. On the basis of regression analysis with least squares technique, the mathematical models between rebounding values, ultrasonic velocity values, rebounding-ultrasonic method values and concrete compression strength were set up by three kinds of functions’ regression analysis. The error analysis showed that the rebounding-ultrasonic non-destruction detecting testing method has higher precision results and the practical value.
