Factors influencing the performance of rebound hammer used for non-destructive testing of concrete members: A review

Case Studies in Construction Materials, 2021
Non-destructive testing (NDT) has a vital role in finding surface hardness of concrete members. B-Proceq curve can calculate the concrete strength by providing statistical correlations between the destructive and the non-destructive strength.
