Concrete Compression Strength Non-Destruction Detecting with Rebounding and Ultrasonic Synthesis Method

Abstract:

Regional materials and mixing ratio in Datong region are used to make the concrete testing blocks. The rebounding and ultrasonic non-destruction detecting testing for concrete compression strength were done by using the six types of strength grades concrete standard specimens according to the technical regulation. By using the common software Matlab7.0, 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 had higher precision results and was used firstly when the conditions were permitted, compared with the rebounding testing method or the ultrasonic testing method.
