This paper proposes a method for the new energy rebound instrument testing compressive strength of structural concrete, it expounds the differences between the hammer and the principle of instrument work normal rebound. Based on the test data,the article gives the conversion between the two rebound hammer values to detect concrete pouring side under the condition of test at the level of the formula. At the same time, it was developed the strength measuring curves by using the energy rebound tester for the detection of concrete pouring the side surface and the bottom surface of the concrete. At last,the test of concrete test hammer bottom surface energy value of the regression relations and the corresponding concrete side test value of the correction formula is given, the pouring of concrete.The results can be reference for the engineering quality detection and control.
