Abstract: Since the nineteen nineties, high strength concrete technology was developing rapidly in our country. However, high-strength concrete detection technology is relatively backward. According to the characteristic of the pumping concrete in Tangshan area and the requirements of JGJ/T23-2001, The paper adopted representative materials of Tangshan to divide high strength concrete test blocks which strength grade is from C50 to C80 into 4 ages of 14 days, 28 days, 60 days and 90 days, then adopted high strength concrete rebound apparatus to experimental research by the rebound method. At last, the test data was collected, and applied regression analysis theory, then used the principle of least square method for regression analysis. The optimal pumping concrete strength rebound curve formula could be obtained.
