Preliminary Investigation on Stregnth Testing Method with Combined Ultrasonic-rebound and Core-drilling Technique

Based on the principle of ultrasonic-rebound and core-drilling technique for structural concrete strength testing,a new strength testing method with the combination of ultrasonic-rebound and core-drilling technique is presented and investigated.The values of correlative parameters are achieved based on theoretical analysis and statistic method.Practical examples prove that the proposed method has characteristics of high accuracy,little damage and low expenses,so the method can be popularized in civil engineering such as bridge,foundation,etc.
