Simple and effective hydrophobic impregnation of concrete with functionalized polybutadienes

In order to extend the life of concrete, various impregnation methods are used to protect it from the damaging effects of external factors. This article proposes an easy and effective method of waterproofing concrete using functionalized polybutadienes. The effects of chemical structure of polymers as well as the type of solvent used, on the hydrophobicity of modified concrete were evaluated. The effectiveness of impregnation was assessed based on the water contact angle measurements and water sorption experiments. For the best hydrophobizing preparation, the water absorption was reduced by 94% compared to the absorption for the unmodified sample.
