Abstract:
The present paper deals with the utilization of the ultrasonic method to evaluate the properties of high performance concrete. The compressive strength and the elasticity module of the concrete are evaluated. A comparative study was performed with the results obtained in the test with the ultrasonic method and in the test with strain gages. The latter were then compared with the elastic module estimated in accordance with the CEB 90 [1] and the NBR 6118 [2] equations. The study shows that test with the ultrasonic method is sensible to variations in the mechanical properties of concrete. Furthermore, the comparative study showed that the elasticity module of concrete may be estimated indirectly by the ultrasonic pulse velocity.
