High-performance repair mortars for application in severe weathering environments: frost resistance assessment

Popis výsledku v původním jazyce

Frost is one of the main degradation processes affecting historic buildings in cold environments. Lime mortar is particularly sensitive to degradation by freeze-thaw cycles due to its high porosity and low mechanical resistance. The aim of the present research is to assess the frost resistance of seven lime-based mortars to be used in repairs. Mortars with different binder composition and a traditional hydrophobic additive were tested. Specimens with three months of age were subjected to freeze-thaw cycles and the ageing action was evaluated by means of mechanical and physical measurements. Improved durability of lime-based mortars with hydraulic binders and linseed oil additive has been confirmed and the different mortar formulas may be promising forrepairs according to specific environmental conditions.
