Abstract:: By analyzing a large amount of test data, the correlation between concrete anti -folding strength and ultrasound and rebound test indicators was established, and the effects of on -site test conditions on the test results were studied in detail. Formulate a set of practical concrete intensity ultrasound and comprehensive test method. After the on -site measurement, the test speed is fast, easy to use, and the error is within 15%, which can meet the practical needs of engineering.
