AbstractAnalysis of the saturation coefficient test results concluded that while the reproducibility is better than + or - 0.015, considerable variation exists within a given brick and among bricks originating from the same production lot. The value of the saturation coefficient was also found to be strongly dependent on the size of the specimen. The test suffers not only from uncertainties but is based on assumptions inconsistent with the recently developed theory of freeze-thaw durability. The freeze-thaw test was found to yield greatly improved results when dimensional changes were monitored. The prediction of frost resistance by another test based on the measurement of the nitrogen surface area correlates well with field performance.
