Sodium sulphate test on lime-based mortars: attaining degraded material to test conservation products and assessing salt resistance
Original language description
Four mortar mixtures were subjected to a sodium sulphate test, formulated to obtain degraded material for the further testing of conservation products and to estimate its salt resistance based on their hydric and hygric parameters. The ageing test involves cyclic conversion of thenarditemirabilite. The cycle comprises of: the drying stage, salt absorption by capillarity, cooling and finally a total immersion in water. Water absorption by capillarity and microporosity determined by mercury porosimetry, were found to have a significant effect on the amount of salt absorbed consequently reflecting the induced damage. The experimental results support the theoretical view that micropores smaller than 0.1 ?m in radius have a critical influence on the damageinduced by sodium sulphate. Lime-metakaolin mortar proved to be extremely salt-susceptible in respect to lime mortar. The addition of linseed oil to both lime and lime-metakaolin mortar improved the salt resistance of both materials by gr
