Freeze-thaw durability of mortars was evaluated using a unidirectional freeze-thaw cycling cabinet. Mortars were first evaluated in prism specimens then as mortar bedded in stone masonry walls. Failure was determined by visual assessment and by measurement of expansion. Three freeze-thaw temperature cycles have been used, to promote different degrees of failure.
