Abstract
This report describes the basic theory of sound applied in the main objective of determination and measurement of velocity of ultrasonic pulses in concrete for estabilish a relationship between pulse velocity and compressive strength of concrete. The compressive strength of standard concrete is determined by tests on cylindrical specimens (H/D=2) drawn from in-situ beams after mesuring pulse velocity. The information previously available is exploited to analyse the statistical relation of regressiono and to determinate the correlation coefficient of distribution.
