Parameters Describing the Coupled Water and Nitrate Transport and Storage in Materials of Historical Masonry

Popis výsledku v původním jazyce

Coupled water and nitrate transport in two materials typical for historical masonry, namely sandstone and lime plaster, is studied in the paper. For the analyzed materials, measurement of basic physical properties is done at first. The transport phenomena are investigated in the conditions of one-sided potassium-nitrate water solution uptake into the rodshape samples having dimensions of 20 x 40 x 160 mm. Moisture diffusivity and nitrate diffusion coefficient are determined using an inverse analysis of experimentally measured moisture and nitrate concentration profiles. Within the inverse analysis, the diffusion-advection mode of nitrate transport is assumed and the effect of salt ions binding on the pore walls of researched materials is taken into account. The measurement of nitrate binding isotherms necessary for the inverse analysis is done using an adsorption method.
