Analysis on the Nondestructive Testing Method of Concrete Strength

Abstract:

Preliminary study the damage of concrete beam by the ultrasonic-rebound method.The contents of the ultrasonic-rebound method are shown below: the concrete rebound value was determined by Rebound method and the ultrasound propagation time in concrete beam was determined by ultrasonic meter to calculate the ultrasonic velocity value in concrete, finally based on the concrete rebound value and the ultrasonic velocity value to confirm the strength of concrete beam.Because of a single rebounding or ultrasonic method is limit in theory and application, and lead to the defect in the application. But the ultrasonic-rebound synthetic method is much better than the above two methods respectively, and it improves the testing precision to apply to the engineering practice.
