Measurement and analysis of salt transport in building materials fully saturated by water

Popis výsledku v původním jazyce

Historical masonry structures usually suffer from harmful salt and moisture action that together with environmental conditions negatively affect their performance, functionally, and durability. The results of deterioration processes attributed to salt first appear on the surface of building elements, most often in plastering and rendering mortars. However, as the salt sources are mostly identified in masonry materials themselves, it is necessary to understand salt transport and storage in base materials to get valuable and crucial information for application of repair mortars and other surface treatments. Therefore, transport and accumulation of dissolved chloride ions in materials frequently used in the Europe for historical masonry, i.e. ceramic brick and sandstone, was investigated. The fully water-saturated samples of the studied materials were penetrated by NaCl solution. The transport of chlorides was characterized by diffusion coefficient considering the chloride interaction with the porous system of the studied materials. An inverse approach to experimentally measured chloride profiles was used to calculate the chloride diffusion coefficient, while the transport of chloride ions was described by a simple diffusion and diffusion-advection model.
