AbstractClay bricks from several sources were found to be in a stressed condition, as indicated by their length changes that apparently resulted from stress relief. The stress, attributed to the firing of the bricks during manufacture, varied in amount from very low values to a maximum estimated to be about 12.0 N/mm[2]. Residual stress was also found in old bricks recovered from demolished buildings; their stressed condition apparently did not affect the performance of the brickwork.
