AbstractPrevious laboratory freeze-thaw tests on a particular dry-press brick resulted in their deterioration after relatively few cycles. In a test made on 11 of these bricks they all failed between 11 and 32 cycles, the average being 20 cycles. Quite the oppostie reports have come from field studies where satisfactory durability is indicated in an area subjected to severe driving rains and an above average number of freeze-thaw cycles during the winter season. This contradiction raises a question concerning the correlation between laboratory tests and natural freeze-thaw action.
