Hydrophobization of dense and fine concrete by polysulfide solutions

The results of research on hydrophobic impregnation of dense concrete with composition ?Aquastat? designed for manufacture of road and airfield plates are presented. It was found that after having been treated with waterrepellent agent the concrete sample is resistant to wetting, i.e. it gets hydrophobic properties. At the same time the water absorption of the samples treated for 24 hours at atmospheric pressure is reduced in three times, and soaked for 0.5 hours under vacuum decreases 5.5 times.
