TIME-DEPENDENT BEHAVIOR OF CONCRETE MADE WITH HAWAIIAN AGGREGATES

THE RESULTS FROM EXPERIMENTAL STUDIES ON CREEP AND SHRINKAGE BEHAVIOR OF AXIALLY LOADED CYLINDERS AND THE CAMBER AND DEFLECTION BEHAVIOR OF SIMPLY SUPPORTED RECTANGULAR PRESTRESSED CONCRETE BEAMS ARE REPORTED. THE NOMINAL COMPRESSIVE STRENGTH OF THE HAWAIIAN AGGREGATE CONCRETE IS 5,000 PSI. THE SPECIMENS WERE STORED AT 73 DEG. F AND 50 PERCENT RELATIVE HUMIDITY. TWO LIGHTWEIGHT AND ONE NORMAL-WEIGHT CONCRETE MIXES WERE USED TO MANUFACTURE THE SPECIMENS. THE CYLINDERS WERE LOADED TO 0.25, 0.40, AND 0.60 COMPRESSIVE STRENGTH. THE BEAMS WERE LOADED AT THIRD POINTS WITH 750-LB LOADS. THE SPAN LENGTH OF THE BEAM WAS 15 FT. HAWAIIAN AGGREGATE CONCRETES SHOW LARGER ULTIMATE SHRINKAGE STRAIN WHEN COMPARED WITH DATA IN PUBLISHED LITERATURE. HAWAIIAN LIGHTWEIGHT CONCRETES HAVE SMALLER ULTIMATE SHRINKAGE STRAIN THAN DOES THE HAWAIIAN NORMAL-WEIGHT CONCRETE. /AUTHOR/
