Characterization of the effect of wetting-drying cycles on the behaviour of hydrophilic additives in mineral wool

Popis výsledku v původním jazyce

Salts and water are assumed to damage historical masonry. Therefore, many conservation treatments have been developed by research teams for the consolidation and protection of porous building materials affected by salt attack. Among them, different methods for obtaining effective desalination of historical masonry were proposed, having smaller or bigger disadvantages. Cellulose is the favourite material added to poultices used in desalination, and hydrophilic mineral wool (HMW) is considered as a possible alternative. Thanks to its hydrophilic additive, HMW allows water transport along the fibres, but contrary to cellulose it is an inorganic material, which reduces the maintenance of the poultice. In this paper, behaviour of the hydrophilic additive inrelation to the wetting-drying cycles is studied. Basic characterization of the HMW is performed. Water and chloride absorption coefficients are measured using standard free water uptake experiment. Additionally, moisture profiles are ac
