However, linseed oil has also an important role on the mechanical behaviour of mortars that is strongly dependent on the type of binder. The effect of linseed oil addition in 1.5% by the weight of the binder was studied in two different mortar mixtures: air lime mortar and air lime-metakaolin mortar. The degree and the order of carbonation and hydration reactions were studied by thermogravimetric analysis and flexural and compressive strength were evaluated along curing time: 14, 28, 60 and 90 days. The results point out that carbonation process was slightly improved by the addition of linseed oil whereas the hydraulic effect of the pozzolana metakaolin was reduced. However, it is the lower capillarity coefficient, which involves a water intake reduction that may be reported as the main factor improving the mechanical behaviour of lime with linseed oil mortar exposed to freeze-thaw cycles and hence, its durability in wet and freezing conditions.
