Frost Resistance of Reproduced Mosaic Mortars

Popis výsledku v původním jazyce

Flax oil has been used as mortar-improving admixture since ancient times. The present paper aimed to quantify the effect of flax oil on engineering properties of aerial lime based mortar, which composition was inspired by mortars collected from several Czech and Austrian mosaics form the end of 19th and beginning of 20th century. The oil increased the air content of mortar, its porosity and water repelling ability, but reduced the rate of carbonation and strength. On the other hand, the mortar frost resistance was significantly improved by flax oil. The optimum dosage of flax oil was determined to be 1% by weight of lime hydrate; at this dose the negative and positive effect of flax oil are balanced resulting to the best durability performance of the mortar.
