INTERNAL ELECTRICAL CURING OF PRESTRESSED CONCRETE

THE EFFECTS OF ELECTRICAL CURING ON THE BOND STRENGTH BETWEEN CONCRETE AND PRESTRESSING STRANDS IS STUDIED TO DETERMINE IF FULL SCALE PRECAST PRESTRESSED CONCRETE BEAMS COULD BE PRODUCED UNDER PLANT CONDITIONS. THE TEST DATA INDICATE THAT THE INTERNAL ELECTRICAL CURING METHOD DOES NOT ADVERSELY AFFECT THE QUALITY OF THE CONCRETE NOR THE STRENGTH OF PRESTRESSED CONCRETE BEAMS. NONE OF THE TESTS HAVE REVEALED ANY ADVERSE EFFECTS CAUSED BY INTERNAL ELECTRICAL CURING WHICH WOULD RESTRICT THE USE OF THE METHOD. THE TESTS ALSO INDICATE THAT THE METHOD IS AN EFFECTIVE AND ECONOMICAL METHOD FOR CURING CONCRETE. THE FLEXIBILITY OF THE HEAT OUTPUT MAKES THE METHOD ADAPTABLE TO MANY FIELD CONDITIONS INCLUDING OUTDOOR WINTER CONSTRUCTION. /AUTHOR/
