The influence of artificial resins on water resistance of gypsum materials

The thesis presents the results of laboratory research concerning the influence of combined silicon and epoxy resin supplements on hydrophobic and water resistance features of gypsum materials. For comparative reasons, the first stage concerns the influence of singular modifying preparations. It has been proved that both silicon and epoxy resins introduced to gypsum compositions separately have advantageous influence on hydrophobic and water resistance features of modified gypsum materials. However, they do not protect these materials against destructive water effects. The second stage of the research concerned introducing two preparations that have different modifying characteristics simultaneously. The results prove that this research direction is justified and it allows to obtain gypsum materials with increased hydrophobic and water resistance features, which can be used in higher humidity places.
