AN EXPERIMENTAL STUDY OF MOISTURE MIGRATION IN CONCRETE

IN AN EFFORT TO OBTAIN INFORMATION REGARDING THE NATURE OF MOISTURE MOVEMENT AND RATE OF MOISTURE LOSS IN A PRESTRESSED CONCRETE REACTOR VESSEL (PCRV), AN EXPERIMENTAL STUDY OF MOISTURE MIGRATION IN A PIE-SHAPED SPECIMEN REPRESENTING THE FLOW PATH THROUGH A CYLINDRICAL WALL OF A PCRV WAS INITIATED. AFTER CASTING OF THE TEST SPECIMEN, TEMPERATURE DISTRIBUTION, SHRINKAGE, AND MOISTURE DISTRIBUTION WERE MONITORED FOR APPROXIMATELY 17 MONTHS. AFTER THIS INITIAL TESTING, A TEMPERATURE GRADIENT OF 80 F (44C) WAS APPLIED TO THE SPECIMEN, AND THE ABOVE-MENTIONED MEASUREMENTS ARE BEING CONTINUED FOR AN ADDITIONAL TEST PERIOD OF ONE YEAR. BASED ON THE RESULTS OBTAINED TO DATE IT APPEARS THAT THERE HAVE BEEN NO SIGNIFICANT CHANGES IN THE SPECIMEN'S MOISTURE CONTENT. /AUTHOR/
