SOME ASPECTS OF TESTING FOR FROST RESISTANCE: I-NON-DESTRUCTIVE TESTS FOR DETERIORATION OF CONCRETE SPECIMENS SUBJECTED TO FROST ACTION; 2-NOTES ON THE EFFECT OF MAXIMUM SIZE OF AGGREGATE ON TESTS FOR FROST RESISTANCE

THE FIRST PAPER BRIEFLY DISCUSSES ADVANTAGES AND DISADVANTAGES OF SEVERAL METHODS OF MEASURING DETERIORATION OF CONCRETE SPECIMENS IN FREEZING AND THAWING TESTS. THESE METHODS INCLUDE VISUAL EXAMINATION, MEASUREMENT OF WEIGHT CHANGE, LENGTH CHANGE, RESONANT FREQUENCY AND PULSE VELOCITY. THE CONCRETE USED IN THE TEST SPECIMENS SHOULD BE THE SAME, PARTICULARLY WITH RESPECT TO MAXIMUM SIZE OF AGGREGATE BY WET SCREENING (IN ORDER TO MAKE SMALL FREEZING AND THAWING TEST SPECIMENS) RESULTS IN A LOSS OF CEMENT PASTE, AND MAY ALTER THE AIR-VOID, THERMAL, AND ELASTIC PROPERTIES OF THE CONCRETE. /PCA/
