Concrete strength by combined nondestructive methods simply and reliably predicted
The author's experience in the estimation of concrete strength by combined methods of nondestructive testing is summarized in this paper. Both the traditional well-known rebound hammer and ultrasonic pulse velocity tests were used in the study. Various charts showing the results are presented. All charts show the 95% prediction intervals, thus enabling professionals to predict concrete strength simply and reliably. Unlike other work, the research ended with one simple chart that requires no previous knowledge of the constituents of the tested concrete. The method presented is simple, quick, reliable, and covers wide ranges of concrete strengths. The method can be easily applied to concrete specimens as well as existing concrete structures. The final results were compared with previous ones from literature and also with actual results obtained from samples extracted from existing structures.
