Abstract：According to the characteristics of compressive strength of the infant age concrete,the limitations of the existing non-destructive testing equipments were analyzed. Referring to the method of ASTM C803—82,and studying the influence of different penetrating force values on the precision of the test results on the basis of the penetration resistance principle,a special compressive strength test equipment for infant age concrete was developed. The test results showed that the penetration depth has a good correlation with the compressive strength of 0.3~2.0 MPa,which indicates that the test equipment could meet the precision requirement of testing the compressive strength of infant age concrete.
