RELATION BETWEEN CREEP AND CREEP RECOVERY IN CEMENT PASTE

THE HYPOTHESIS OF SUPERPOSITION OF STRAINS WITH RESPECT TO CREEP AND CREEP RECOVERY IS DISCUSSED IN RELATION TO BASIC CREEP SEPARATED FROM STRESS INDUCED SHRINKAGE AS WELL AS TO FORCED SHRINKAGE AND SWELLING. RESULTS OF TESTS IN COMPRESSION AND IN TENSION ARE REPORTED. CREEP IN COMPRESSION IS SHOWN TO INCREASE THE LOSS OF MOISTURE FROM THE PASTE TO THE SURROUNDING MEDIUM. TENSILE CREEP IS SHOWN TO BE SOMEWHAT SMALLER THAN CREEP IN COMPRESSION AT THE SAME STRESS STRENGTH RATIO, BUT SPECIFIC CREEP IS SIGNIFICANTLY HIGHER IN TENSION THAN IN COMPRESSION. /AUTHOR/
