RAPID FREEZING AND THAWING TEST FOR AGGREGATE
THIS REPORT DESCRIBES A FREEZING AND THAWING PROCEDURE WHICH REQUIRES ABOUT THE SAME TEST PERIOD AS THE SULFATE SOUNDNESS TEST. THE ACCELERATED ACTION OF THIS TEST RESULTED FROM THE USE OF A WATER-ALCOHOL SOLUTION AS THE FREEZING MEDIUM RATHER THAN WATER. A HOME-TYPE FREEZER WAS FOUND TO BE SUITABLE FOR CONDUCTING SUCH A FREEZING AND THAWING PROCEDURE. THE RESULTS OF FREEZING AND THAWING 27 DIFFERENT MATERIALS BY THE WATER-ALCOHOL METHOD SHOWED THAT 16 CYCLES OF THE METHOD ARE EQUAL IN SEVERITY TO 5 CYCLES OF THE SULFATE SOUNDNESS TESTS AND ARE MUCH MORE SEVERE THAN 50 CYCLES OF FREEZING AND THAWING IN WATER. FREEZING AND THAWING IN THE WATER-ALCOHOL SOLUTION, HOWEVER, RESULTED IN A DIFFERENT ORDER OF SOUNDNESS BEING INDICATED FOR THE VARIOUS MATERIALS THAN WHEN WATER WAS USED. THE RESULTS OF THE SULFATE SOUNDNESS TEST DID NOT CORRELATE CLOSELY WITH ANY OF THE FREEZING AND THAWING PROCEDURES. /AUTHOR/
