Lime-based mortars with linseed oil: sodium chloride resistance assessment and characterization of the degraded material

Popis výsledku v původním jazyce

Lime mortar is often used to repair historic buildings but is prone to salt crystallization with deleterious consequences. Lime mortar is a very susceptible material due to its high porosity and low mechanical resistance. Recent findings concerning mortar additives that impart hydrophobic properties to mortar show that by limiting water penetration, damage from frost and salt can be decreased. Linseed oil was commonly used in former times as an additive for mortar in order to grant hydrophobicity. The aim of the present research is to assess the ability of lime -based mortars with 1.5% linseed oil (by the weight of the binder) to resist salt degradation. The effect of linseed oil addition was studied in two different mortar mixtures: air lime mortar and air lime -metakaolin mortar. Specimens, cured for three months, were subjected to a sodium chloride ageing test.
