The present study involves the development of a correlation of Non-Destructive Testing (NDT) and Destructive Testing (DT) techniques for evaluation of concrete strength. The models selected are linear, quadratic, cubic for the present study. Concretes with grades M10 to M40 were used and compressive strength relationships developed between what was obtained from the destructive testing using a compression testing machine and surface hardness measurement gotten through non-destructive testing using a rebound hammer. The analysis showed good correlations, where the coefficients of determination (R) ranged from 91.6% to 97.9% for the different models. This can be used to prove that the NDT, when calibrated on DT data, allows for accurate estimation of concrete strength with very low intrusion and time investment. The study highlights how advanced mathematical models can facilitate more accurate predictions for concrete strength which may decisively determine the safety and durability of larger engineering works.
