Most of the heritage and ancient buildings around the world are made of masonry. Lime mortars are very commonly found in such buildings as the joint between units. Lime-based mortars are also used nowadays because of their environmental friendly characteristics. Understanding the mechanical and durability performance of lime-based mortars is, therefore, very important. While this has been the subject of several studies in previous years, the important role of curing conditions on the durability of lime-based mortars has been neglected. To address this gap, this paper focuses on moisture transport properties in lime-based mortars under different curing conditions, as one of the critical agents in deterioration mechanisms. We specifically present the capillary absorption tests on lime mortar and discuss the results. The results show that the same mortar under different curing conditions has different capillary moisture content and capillary absorption coefficient.
