AbstractSome methods were used to assess the frost durability of clay bricks. Expansion on freezing of saturated bricks provides a valid test for the assessment of their durability. Although criteria based on saturation coefficient and specific surface area are useful, they depend on the raw materials and the manufacturing processes. The optimum firing condition can be estimated from a plot of saturation coefficient against specific surface area. Quality control can be improved if both absorption and saturation coefficient are used together. The current quality control test involving 48 hours can be reduced to one hour or less using short-term absorption tests.
