Abstract
A study has been made of the shrinkage potential and durability performance of a range of mortars made with both high and tow day content sands cast on bricks of varying capillary suction. The effects of the methylene blue value of the sand used, the level of brick capillary suction and the binder content have been related to the performance of the mortar. The results have been compared to previous work studying the effects of clay fines in sand on the performance of mortar. The conflicting benefits of brick capillary suction have been discussed in terms of their effect on shrinkage potential and durability performance.
