DYNAMIC POISSONS RATIO OF PORTALND CEMENT PASTE, MORTAR AND CONCRETE
TESTS ARE REPORTED TO DETERMINE THE POISSONS RATIO OF HARDENED PASTE, MORTAR AND CONCRETE FROM LONGITUDINAL AND TORSIONAL RESONANT FREQUENCIES AND FROM PULSE VELOCITY. IT IS SHOWN THAT POISSONS RATIO DEPENDS ON THE MIX PROPORTIONS, THE TYPE OF AGGREGATE AND ITS POISSONS RATIO, AND THE AGGREGATE VOLUME CONTENT. PULSE VELOCITY POISSONS RATIO IS MORE CONSISTENT AND GREATER THAN THAT OBTAINED FROM LONGITUDINAL AND TORSIONAL RESONANT FREQUENCIES. THE CONSIDERABLE SCATTER FOUND IN POISSONS RATIO VALUES OBTAINED FROM RESONANT FREQUENCY TESTS IS SHOWN TO BE DUE TO ANISOTROPY AND THE IMPERFECTLY ELASTIC BEHAVIOR OF THE PASTE, MORTAR AND CONCRETE. /AUTHOR/
