| Abstract | Hydraulic lime is regaining popularity in restoration work. This paper describes the results obtained from an initial assessment of mortar made using hydraulic limes available in Canada. The emphasis was on resistance to frost damage, a major consideration in Canada's cold winters. The mortars, all air-entrained to improve frost resistance, were tested as part of small stone masonry specimens to more realistically simulateperformance in practice (as opposed to mortar samples on their own). The frost durability was assessed by subjecting the specimens to a uni-directional freeze-thaw test. The results show hydraulic lime mortars with air entrainment have the potential for good performance in terms of freeze-thaw resistance. Factors which influenced freeze-thaw resistance were the type and source of hydraulic lime, length of initial damp curing,mortar compaction, stone wetting before mortar application, and sand grading. |
