Frost resistance of lime-based mortars
Janotová, Dana ; Nunes, Cristiana Lara ; Slížková, Zuzana
The paper presents several methods for assessing frost resistance of six different lime-based mortar mixtures according to the type of binder. Specimens with three and twelve months of age were subjected to frost resistance test according to CSN 72 2452 standard. Durability of each mortar type was evaluated through mechanical strength, frost resistance coefficient, modulus of elasticity and saturation coefficient. The results obtained point out that the lime-based mortar mixtures tested can only fulfil the frost resistance standard requirements if containing a certain amount of Portland cement.
