- Abstract
This article presents the results of a study on the development of an anti-corrosion plaster composite based on water glass with increased electrical conductivity. Known acid-resistant quartz-fluorosilicate composites containing liquid sodium silicate, sodium fluorosilicate and acid-resistant high-silica filler in the form of quartz, andesite or diabase powder were chosen as the prototype. The low water resistance and low adhesion to Portland cement concrete of these composites limits their application. By adding granulated blast-furnace slag to the composite, it was possible to increase the water resistance of the solution and its adhesion to concrete. The addition of graphite filler to the composite made it possible to increase the electrical conductivity. This made it possible to obtain not only a corrosion-resistant (to chemical and physico-chemical corrosion) composite, but also to use it as a grounded protective screen to drain leakage currents from the structure, thus protecting it from both corrosion and electrocorrosion destruction.
