Abstract:Nondestructive test methods (NDT) have been used to evaluate concrete strength using curves that correlate the NDT measurements with the compressive strength of concrete established by a laboratory testing program. Usually the parameters that affect these curves are the water-cement ratio, the aggregate type, the maximum aggregate size, and the cement type of the concrete. This work presents a study on the correlations between the compressive strength of concrete and measurements from three nondestructive test methods: ultrasonic pulse velocity, probe penetration, and rebound hammer. The study included 30 different concrete mixtures made with materials used in the city of Rio de Janeiro. The compressive strength and nondestructive tests were carried out at ages of 3, 7, 14, 28, and 90 days. Analysis of variance (ANOVA) was used to investigate the importance of different parameters on the results of the compressive strength and nondestructive tests. Simple and multiple regression analyses of the obtained results lead to the proposed expressions for evaluating the compressive strength of concretes used in Rio de Janeiro from measurements using one or two nondestructive tests.
