Research on the application of rebound method and ultrasonic rebound comprehensive method in concrete strength testing of hydraulic engineering
When testing the strength of concrete in water conservancy engineering projects,there are often phenomena such as low rebound value and insufficient strength,leading to unqualified concrete strength evaluation.Therefore,when testing the strength of concrete,a reasonable selection of testing methods should be made,and factors that affect the testing results should be avoided to ensure the accuracy of the testing results.Based on this,this article first elaborates on the principles and influencing factors of rebound method and ultrasonic rebound comprehensive method.Then,the two detection methods are analyzed and compared from three aspects:detection environment,concrete age,and compressive strength.Finally,combined with engineering cases,the detection accuracy and deviation of the two methods are further analyzed and discussed,providing reference for the selection of concrete strength detection methods in hydraulic engineering.
