PREDICTION OF CREEP AND SHRINKAGE BEHAVIOR FOR DESIGN FROM SHORT TERM TESTS

SIMPLE EMPIRICAL EQUATIONS ARE PRESENTED FOR PREDICTING LONG-TIME CREEP AND SHRINKAGE PROPERTIES OF CONCRETE. PREDICTION ACCURACY THAT PREVIOUSLY REQUIRED ALMOST 4 MONTHS OF TESTING CAN NOW BE ACHIEVED WITH ONLY 28 DAYS OF CREEP AND SHRINKAGE DATA. GENERAL CONSTANTS ARE PRESENTED FOR USE WHEN THE 28-DAY EXPERIMENTAL PROGRAM IS NOT FEASIBLE. /AUTHOR/
