The pore size distributions of approximately 80 bricks removed from walls of existing buildings were measured using mercury intrusion. These distributions were used to calculate a Durability Factor using the method of Maage. This Durability Factor was then correlated with the observed performance of the bricks on the buildings. It was found that all bricks with a Durability Factor greater than 70 exhibited no freeze/thaw durability problems. Further, with very few exceptions, all bricks with a Durability Factor less than 70 were suffering freeze/thaw failures. This technique is more accurate and faster for selecting potentially durable bricks than the current use of absorption measurements.
