Voznenko S. Hermetic composition on the basis of cement and Coal Tar Resin (CTP) for flooded tunnels

The dissertation is devoted to the decision of a urgent task - сreation of composition and methods for a hydroisolation of flooded tunnels. In work the representations about the mechanism of adhesive strength of protecting сovering to damp and watersaturation to substrates develop. The protecting сovering is сreated which has optimum adhesive strength properties on damp surfaces. It consists of cheap coal tar resin modified by the additive of the epoxi resin ED-20 and cement filler.The protecting сovering has adhesive strength to damp to concrete and mortar substrates not less than 2,0 МPа. The testing of this covering on action of the natural and exploitation factors has confirmed its high durability.
