Název v původním jazyce

Effect of Hydrophobization on The Properties of Lime Plasters with Pozzolanic Admixtures

Popis výsledku v původním jazyce

The hydrophobization of the three studied lime-pozzolana plasters using zinc stearate resulted in the following changes of their basic, mechanical and hygric properties. The open porosity of the hydrophobized plasters decreased significantly and their bulk density increased. The compressive strength and the bending strength of the lime-metakaolin plaster decreased only moderately after hydrophobization but for the lime-grinded brick plaster and the lime-grinded enamel glass plaster these were down to three times lower. The water vapor sorption of lime-metakaolin plaster decreased about four times after hydrophobization but the corresponding decrease for the remaining two lime-pozzolana plasters was only 30-40%. The water vapor diffusion factor of the lime-metakaolin plaster was not changed in a significant way due to the hydrophobization, for the remaining two plasters there was an increase of about 50%. The liquid water transport properties of all three studied plasters decreased sig.
