PREDICTION AND ASSESSMENT OF CONCRETE PROPERTIES FROM PULSE-VELOCITY TESTS

A study has been made of the feasibility of applying multiphase theory to the interpretation of pulse-velocity tests. This included a general examination of certain non-destructive test parameters. It was found that the stiffness constant is a better index for the assessment of the dynamic modulus of elasticity than the pulse velocity and also that it reflects the elastic modulus of other materials. It was also found that the calculated propagation velocity through the cement-paste phase gave better correlation with crushing strength and modulus of rupture than the pulse velocity through the concrete. The relationship is influenced by the type of aggregate, but there is indication that aggregate groupings could be used since the results for some aggregates of different types were found to lie reasonably under one curve. It is suggested that multi-phase interpretation of pulse-velocity tests could be used to examine the property and behavior of mortars and of cement-paste phases in concretes. /Author and TRRL/
