The standard and non-destructive tests were performed on totally 144 cubes and 24 beam specimens
produced from different concrete mixtures. The results of the non-destructive tests carried out on
beams were correlated with cube compressive strength values. The effects of aggregate’s type and its
maximum size on the results of ultrasonic pulse velocity and rebound hammer tests were investigated.
Simple charts were obtained from the test results and the use of these charts for the quality control of
concrete in structural elements cast by locally available materials was discussed. Strength estimations
were made using five combined models proposed by various investigators. The estimated strength
values were compared with experimental values.
