| Abstract | Leakage and bond-strength tests on small brick panels have indicated a weaker bond between a mortar bed and the brick above than between the mortar bed and the brick below. Loss of moisture from fresh mortars to bricks was studied in an effort to explain this difference. Loss of moisture from three mortars having different water retentivity values was determined after timed intervals of contact with bricks having different rates of suction. Moisture loss increased with the suction rate of the brick, except for brick with very high suction rates. The effect of moisture loss on the plasticity of the mortar is then considered, and the presence of a moisture gradient in the mortar bed is indicated. The pattern of moisture loss to bricks having similar suction values but manufactured with different materials and by different processes is also investigated. Results are discussed in the light of field observations of masonry construction practices. |
