THE EFFECT OF MIX PROPORTIONS AND METHOD OF TESTING ON POISSONS RATIO FOR MORTARS AND CONCRETES

FOLLOWING RECENT STUDIES OF CONCRETE AS A COMPOSITE MATERIAL, THIS PAPER EXAMINES WHETHER THERE IS A RELATION BETWEEN THE MIX PROPORTIONS AND PROPERTIES OF THE CONSTITUENTS AND THER OVER-ALL POISSONS RATIO FOR MORTARS AND CONCRETES. FROM AN EXAMINATION OF AVAILABLE AND NEW DATA, IT IS APPARENT THAT POISSONS RATIO IS AFFECTED BY THE METHOD OF TESTING, THE MIX PROPORTIONS, AND THE MOISTURE CONDITION AND TEMPERATURE OF THE SPECIMENS. APPROXIMATE EXPRESSIONS ARE PROPOSED FOR THE STATIC AND DYNAMIC POISSONS RATIOS OF SATURATED MORTARS AND CONCRETES MADE WITH GRAVEL AGGREGATES IN TERMS OF THE VOLUME FRACTIONS AND POISSONS RATIOS OF THE CONSTITUENT AGGREGATE AND CEMENT PASTE PHASES. STATIC AND DYNAMIC TESTS DO NOT MEASURE THE SAME PROPERTIES OF CONCRETE, AND SUGGESTIONS ARE MADE FOR THE DIFFERENCES BETWEEN THEM. /RRL/
