BASIC AND DRYING CREEP OF CONCRETE

FROM THE GEL COMPLIANCE FACTOR AND A CREEP PARAMETER INOLVING THE VOLUME CONCENTRATIONS OF GEL AND OF CEMENT PASTE AND USING A HYPERBOLIC CREEP-TIME EXPRESSION, AN EXPRESSION FOR CREEP IS DERIVED. THIS INDICATES THAT CREEP IS PROPORTIONAL TO THE STRESS-STRENGTH RATIO AND INCREASES WITH AN INCREASE IN THE VOLUME OF GEL AND, IN THE CASE OF DRYING CREEP, WITH CONCURRENT SHRINKAGE. TEST RESULTS ON CONCRETES MADE WITH TYPE 1 CEMENT ARE PRESENTED AND ANALYZED WITH RESPECT TO THE PROPOSED EXPRESSION. IT IS SHOWN THAT CREEP RECOVERY IS HIGHER UNDER WET STORAGE CONDITIONS THAN AT A RELATIVE HUMIDITY OF 50%. THE TIME NECESSARY FOR THE RECOVERY TO BE COMPLETE IS AT LEAST 100 DAYS. /LCPC(A)/RRL/
