Streszczenie
The aim of the research presented in the paper was to evaluate the feasibility
of using hydrophobizing preparations based on organosilicon compounds for
impregnation of ceramic bricks. The process of surface hydrophobization both
using solvents and water substances was analyzed. The effectiveness of four
preparations which differed in terms of hydrolytic polycondensation degree,
viscosity and concentration, as these are the factors that are decisive as far as the
end result of hydrophobization is concerned.
The following laboratory tests were performed: the analysis of physical properties
of the tested materials, water drop absorption test, water absorption by weight of
the hydrophobized samples, water vapour diffusion, frost resistance, the analysis
of silica gel properties in electron microscopy.
Based on the results of the above mentioned, the analysis of effectiveness and
desirability of hydrophobization using emulsion with a low VOC content was
carried out.
