ELECTROCONDUCTIVE COATING BASED ON PORTLANDCEMENT FOR ELECTRIC CORROSION PROTECTION AND REPAIR OF CONSTRUCTIONS AND FACILITIES OF RAILWAYS

Annotation. Purpose. Development of conductive warehouse on the basis of Portland cement for repair and screen protection against electric corrosion of constructions and structures of railways. Methodology. The electrical characteristics of the coatings and their efficiency (the ability to reduce the currents flowing through the design) were investigated using original author's techniques and laboratory settings. Findings. Solutions with low electric resistance are considered, which are potentially able to protect against the destructive effect of excess electric charge by reducing the leakage currents through the construction material. Originality. Experimental dependences of strength and electric characteristics of graphite-filled compositions of permeable action on their composition are established; intervals of component costs, within which achieve the best performance and feasibility. Practical value. According to research results, a graphite-filled composition for the protection of buildings and structures of railway transport from electro-corrosion has been developed and implemented. The technology of preparing the composition and protecting it from concrete and masonry construction is developed. The research results are introduced in the development of structural and technological solutions for the restoration of operational properties and protection against corrosion of buildings of the station complexes of the Southern Railway.
