From the standpoint of structural performance of the interventions it is essential to have knowledge of time dependent deformations of masonry which are mainly drying shrinkage and creep. As the moisture movement into capillaries is the driving force for both phenomena, the combined effects of exposure to drying and sustained loading on constituents of brick masonry are studied. These constituents are full bricks and mortars made of cement and pozzolanic materials. The parameters investigated in this experimental work are: 1. Mortar consistency 2. Thickness of mortar joint 3. Thickness of bricks 4. Curing conditions.
