Effect of Salinization on Hygroscopicity of Lightweight Mortars with Zeolite

Popis výsledku v původním jazyce

Rendering and plastering mortars designed for repair of masonry are often exposed to harmful conditions, whereas salt weathering represents serious risk for mortars durability and functional performance. Due to their nature, inorganic salts are highly hygroscopic substances which must be always considered in the case of the salt-contaminated building materials. In the presented research, structural and thermal parameters of lightweight mortars with zeolite aggregate were tested. The assessment of sorption/desorption isotherms which were experimentally measured and analyzed was of the particular importance. Fort the measurement, the static desiccator method combined with precise laboratory balances was used. Before the hygroscopicity analysis, the samples went through the salt crystallization test which was conducted by the use of NaCl water solution. In this way, salinization of samples was reached. The results obtained showed a significant increase in sorption capacity due to the used lightweight aggregate (zeolite) and the presence of salt in the pores of the mortars.
