    Abstract

    A detailed seven-year study has been made of the moisture expansion of clay products, with special emphasis on bricks and the consequent damage to brickwork. Methods have been developed for measuring the expansion of bricks and brickwork under varying conditions of exposure. These methods are described, and the results are briefly discussed with reference to the influence of various factors on the rates and magnitude of expansion. Finally, the possible causes and kinetics of expansion are considered and estimates made of the likely maximum expansion of brickwork. Results have shown that bricks expand on leaving the kiln, and expansion of brickwork in buildings can reach more than 2 in. per 100 ft.
