TEMPERATURE VARIATION AND MOISTURE RETENTION OF CONCRETE CURING METHODS

ELECTRICAL METHODS WERE UTILIZED TO DETERMINE VARIATIONS IN TEMPERATURE AND MOISTURE AS A FUNCTION OF THE DISTANCE FROM THE SURFACE OF THE SLAB. THE RELATIVE MERITS OF THE FOUR CURING METHODS: LIQUID-MEMBRANE SEAL, LIQUID-MEMBRANE SEAL COVERED WITH A LIMEWASH, WATERPROOFED PAPER, AND DAMP BURLAP WERE INVESTIGATED. FOR COMPARISON, SLABS WITHOUT ANY ARTIFICAL CURING WERE INCLUDED. VIRGINIA ROAD SPECIFICATIONS WERE FOLLOWED WHEN APPLICABLE. TEST SECTIONS WERE REPEATED AND PLACED IN REGULAR AND AIR-ENTRAINED CONCRETE. RESULTS INDICATE THAT OVERALL VARIATIONS IN TEMPERATURE AND MOISTURE WERE LARGER AND MORE FREQUENT NEAR THE SURFACE WHILE THE BOTTOM OF THE SLAB VARIED LITTLE AND INFREQUENTLY. A RELATION WAS ESTABLISHED BETWEEN THE OVERALL VARIATIONS AND CLIMATIC CONDITIONS. NO MAJOR DIFFERENCE IN THE EFFECTIVENESS OF THE CURING METHODS ON THE REGULAR AND AIR-ENTRAINED CONCRETE COULD BE OBSERVED. FROM THE RESULTS, THE ORDER IN WHICH THE METHODS PROVED THEMSELVES BEST ABLE TO RETAIN MOISTURE WAS, ON THE AVERAGE: WATERPROOFED PAPER, DAMP BURLAP, LIQUID-MEMBRANE SEAL WITH LIMEWASH, LIQUID-MEMBRANE SEAL, NO CURE. RECORDS INDICATE THE AVERAGE ORDER OF EFFECTIVENESS TO MAINTAIN LOW AND UNIFORM TEMPERATURES TO BE: LIQUID-MEMBRANE SEAL WITH LIMEWASH, DAMP BURLAP, WATERPROOFED PAPER, NO CURE, LIQUID-MEMBRANE SEAL. /AUTHOR/
