CREEP AND SHRINKAGE IN LIGHTWEIGHT CONCRETE

DATA ARE GIVEN FOR A LARGE NUMBER OF LABORATORY INVESTIGATIONS THAT HAVE BEEN MADE ON CREEP AND SHRINKAGE IN STRUCTURAL QUALITY LIGHTWEIGHT AGGREGATE CONCRETE. THE AGGREGATES ARE UNCOATED EXPANDED SHALES AND A CLAY PRODUCED IN TEXAS BY THE ROTARY KILN PROCESS. A STUDY IS MADE OF THE EFFECTS OF VARIATIONS IN THE TYPE OF CEMENT AND THE CEMENT CONTENT, THE TYPE OF AGGREGATE AND THE AGGREGATE GRADATION, WATER CONTENT, AIR CONTENT, MIXING TIME, AGE AT TIME OF LOADING, LEVEL OF SUSTAINED COMPRESSIVE STRESS, AND EXPOSURE CONDITIONS. A COMPARISON IS MADE BETWEEN VALUES OBTAINED FROM LABORATORY SPECIMENS AND FROM A FULL-SCALE PRESTRESSED CONCRETE BRIDGE HAVING ONE SPAN OF LIGHTWEIGHT CONCRETE AND ONE SPAN OF SAND-GRAVEL CONCRETE. RECOMMENDATIONS ARE MADE FOR APPLYING LABORATORY DATA TO DESIGN CONDITIONS. /AUTHOR/
