    Abstract

    Mortars containing normally hydrated dolomitic lime caused greater expansion of brickwork piers than other mortars. Because the expansion of brickwork was much greater in the vertical direction than horizontally, however, and because the expansion was inhibited greatly by a relatively slight load, mortars containing normally hydrated dolomitic lime did not damage the brickwork from their expansion. The results of this study offer an explanation for the satisfactory performance of brick buildings with mortars containing normally hydrated dolomitic lime even though such mortars have great capacity for expansion.
