PRELIMINARY REPORT ON AN INVESTIGATION INTO THE INFLUENCE OF SEVERAL FACTORS ON THE SODIUM SULPHATE SOUNDNESS TEST FOR AGGREGATE

DIFFERENT ENVIROMENTS IN WHICH AGGREGATE MAY BE USED ARE LISTED AND THE FACTORS WHICH MAY LEAD TO DETERIORATION OF AGGREGATE OF ANY ROCK TYPE ARE SUMMARIZED. FROM THE TESTS CARRIED OUT IT IS CONCLUDED THAT IF THE TEMPERATURE CONDITIONS, FREQUENCY OF WETTING AND DRYING AND THE IMMERSION MEDIA ARE KNOWN, THE APPROXIMATE LIFE OF AGGREGATE UNDER SEVERE ENVIRONMENTAL CONDITIONS CAN BE CALCULATED. THE 5-CYCLE SODIUM SULPHATE TEST IS PROBABLY TOO SEVERE FOR SIMULATING RESPONSE TO NORMAL AUSTRALIAN ENVIRONMENTAL CONDITIONS IN WHICH AGGREGATE IS USED. REFERENCE IS ALSO MADE TO TEMPERATURE AND TENSILE STRENGTH OF CORE SPECIMENS TESTED. /RRL/
