SOME PROPERTIES OF CONCRETE MADE ON FIVE CONSTRUCTION SITES

摘要

A number of site investigations has been made to assess the quality of concrete in structural members using ultrasonic testing equipment. In the course of this work it has been possible to obtain correlated values of equivalent cube strength, cylinder strength, modulus of rupture, static and dynamic modulus of elasticity and dynamic Poisson's ratio for individual types of concrete;the average results have been collected and tabulated for record purposes.
