摘要：
In this paper, the feasibility of using rebound test with light hammer in determination of compress strength of high strength concrete in site has been discussed based on the repetition, accuracy and differentiability of the testing. A great number of concrete samples with compress range from C50 to C 100 have been tested in laboratory The test data have been statistically calculated based on regression analysis. The results show that the rebound instrument with light hammer is practical in determination of compress strength of high strength concrete in site because of its lower data differentiability, better repetition and more accuracy comparing with those of rebound instrument with heavy hammer.
