A STUDY ON THE CAUSES OF VOLUME CHANGE OF CEMENT PASTE /IN FRENCH/

THE DRYING SHRINKAGE OF HARDENED CEMENT-PASTE SPECIMENS VARYING IN THEIR PHYSICAL PROPERTIES WAS INVESTIGATED AT CURING TEMPERATURES RANGING FROM NORMAL TO HIGH. WATER VAPOR ABSORPTION TESTS AND DRYING SHRINKAGE TESTS WERE CARRIED OUT ON SPECIMENS IDENTICAL IN SIZE AND MIX-DESIGN AND CURED UNDER THE SAME CONDITIONS. IT WAS CONCLUDED THAT DRYING SHRINKAGE IS PROPORTIONAL TO THE STRENGTH OF CAPILLARY TENSION AND TO THE AMOUNT OF EVAPORABLE WATER HELD AT EQUILIBRIUM IN A UNIT VOLUME OF PASTE AND INVERSELY PROPORTIONAL TO THE DYNAMIC YOUNG'S MODULUS. THE SHRINKAGE DUE TO THE ESCAPE OF COLLOIDAL PORE WATER IS PROBABLY CAUSED BY VERY LOW RELATIVE HUMIDITY. /LCPC/(A)RRL/
