    Abstract

    In the present paper the errors in compressive strength estimation when the ultrasonic method is applied to conventional and recycled concretes are evaluated. Tests were performed on laboratory prototypes made with conventional concretes containing natural coarse aggregates and on recycled concretes containing 75% of recycled coarse aggregates (crushed concretes) by volume. In both types of concrete the strength was estimated by employing previously obtained correlation equations between the ultrasonic pulse velocity and compressive strength measured on concretes made with the same materials. The results from both types of concrete indicate that the errors in the estimated strength can be considered technologically acceptable.
