CONTRIBUTION TO THE MACROSTRUCTURAL THEORY OF THE STRENGTH OF A CONCRETE AT RUPTURE BY PURE COMPRESSION /IN FRENCH/

A MACROSTRUCTURAL HYPOTHESIS AS TO THE RUPTURE STRENGTH OF CONCRETES SUBJECTED TO A SIMPLE COMPRESSION TEST IS PRESENTED, BASED ON A POSSIBLE FORM OF RUPTURE AT THE LIMIT STATE, OBTAINED BY ELIMINATING THE SURFACE FRICTION BETWEEN THE PLATES OF THE PRESS AND THE TEST PIECE BASES. THE MACROSTRUCTURAL HYPOTHESIS HAS RECOURSE TO THREE FUNDAMENTAL PARAMETERS: THE SPLITTING STRENGTH OF THE AGGREGATE, THE TENSILE STRENGTH OF THE MORTAR OR THE HARDENED CEMENT PASTE, AND THE ADHESION BETWEEN THE AGGREGATE AND THE HARDENED CEMENT PASTE OR THE MORTAR. EXPERIMENTAL RESULTS ARE GIVEN SHOWING THE PART PLAYED BY THE FRICTION OF THE PLATES OF THE TESTING MACHINE IN THE ESTIMATION OF THE STRENGTH OF A CONCRETE AT RUPTURE BY PURE COMPRESSION. WITH EQUAL DIMENSIONS OF THE AGGREGATES THE STRENGTH OF THE CONCRETE INCREASES WITH THE DIMENSION OF THE TEST PIECE, AND NOT THE REVERSE AS IS GENERALLY ASSUMED. /DOT/
