Abstract

This paper describes the fundamentals of the theory of sound applied with the main objective of determining and measuring the velocity of ultrasonic impulses in concrete to establish an empirical relation between the velocity of propagation of the impulses and the compressive strength of concrete. The compressive strength of a standard concrete is established with tests on cylindrical specimens (H/ D= 2) taken in-situ from beams, subsequently to the measure of velocity. The information previously available is used for the statistical analysis of regression and for the determination of the coefficient of correlation of distribution.
