摘要：
The physical and chemical characteristics of hydrophobic protection of cement rock and concrete surfaces, using the binders based on polyurethane, elemental sulfur, and nanodimensional fillers of Tarkosil and thermally modified peat, are discussed. It is shown that a combined use of the physical texture-formation methods and an optimal selection of the protective coating chemical composition results in a significant increase of the wetting angle and the solid phase surface energy. It is found out that a directional orientation of the magnetically sensitive particles in the magnetorheological composites in a magnetic field is among the most effective methods for improving the protective coating properties.
