ABSTRACT
In the course of service, glued joints of building structures are exposed to attack by water and other corrosive media. Glued joints of polymer concrete and polymer-silicate concrete in chemically stable prefabricated structures are constantly exposed to aggressive media at elevated temperatures. This chapter discusses an experiment to study the chemical stability of polymeric adhesives and glued joints made with epoxides and modified polyester-acrylates. The chemical stability of polymer-cement adhesives was not examined because they are not recommended for use in structures exposed to aggressive media. It emphasizes that the stability of the adhesive in the aggressive medium must always be higher than that of the materials to be glued. The chapter presents the method used for determining the average service life of pickling baths with multilayer protection and for developing the polymer-silicate-concrete baths inducted at the Volgograd Steel Wire and Cable Plant and the Lepse Metal Grid Plant at Solnechnogorsk.
