Ultrasonic testing concrete defect verification test

Three sets of 11 blocks of the same size 100*100*100 were designed and tested by nonmetal ultrasonic detector. The concrete test blocks with different artificial defects were tested. The test shows that the concrete contains 20mm diameter. Ultrasonic testing can effectively detect the tube; ultrasonic for the 5-day,20-day ultrasonic testing, the value of the analysis found that the 20-day test results are more stable; for the interior of the concrete containing the pockmark, the ultrasonic test can not be carried out Effective detection.
