Development of polymer coating filled with anthropogenic waste for building structures protection

The results of developing protective polymer coating characterized by high strength and containing galvanic waste are presented. This coating is designed to protect concrete and metal surfaces of various building structures against adverse natural and external impact. The coating is developed basing on polymethylphenylsiloxane binder, tetraisopropyltitanate hardener and anthropogenic waste - galvanic sludge - used as the filler. The application of polymethylphenylsiloxane as a binder improves heat-resistant properties of the resulting coating and reduces its water absorption. Galvanic sludge in an amount of 5-15 wt. allows increasing the coating strength properties and reducing its cost, meanwhile solving another important issue - safe disposal of galvanic sludge.
