Object of research - the concrete and mortar concrete, reinforced concrete and masonry structures of buildings and grounds under-rail, which operate on electrified lines, concrete optimal formulations, protective coatings. Subject of scientific research - the restoration and protection of structures of buildings and grounds under-rail against the negative influence of leakage currents and stray currents on electrified railways. The work purpose - to develop new theoretical and experimental basis for the protection against the negative influence of leakage currents and stray currents in the concrete and mortar concrete, reinforced concrete and masonry structures of buildings and grounds under-rail, which operate on electrified railways. Methods, tools and procedures for solving work: an analytical review of existing theoretical concepts, research methods and measurement electrocorrosion and corrosion resistance, protection of structures and facilities - the formulation of working hypotheses - theoretical and experimental evidence for hypotheses - their adjustment to the theoretical concepts. To ensure the reliability of the results of experimental studies carried out physico-mechanical tests, as well as the use of physical-chemical, colloid-chemical, electrochemical methods of research. As a result, research results are as follows: - A number of new scientific hypotheses on the distribution of the electric field with the electrified railway to nearby buildings of them and electrocorrosion cement and concrete actions on the field - improvements to existing and developed original research methodologies and Metrics electrocorrosion and corrosion resistance - developed comprehensive tools and design for protection from electrocorrosion concrete, reinforced concrete and masonry structures - adjusted physical and mathematical models electrocorrosion and properties change over time - developed recommendations for the protection of designs of buildings and grounds under-rail against the negative influence leakage currents and stray currents on electrified railways. Implementation of research results will allow for the implementation of surveys of collapsing structures of buildings and grounds under-rail railways with the help of new measurement techniques to predict their actual life, to develop effective ways to protect them from electrocorrosion. The economic effect of actual life prediction and prevention of adverse effects of leakage currents and stray currents in the concrete and mortar construction of buildings and grounds under-rail will be provided by lower costs for their maintenance, continuation of their service life, higher reliability, durability and safety. Keywords: concrete, mortar, concrete, reinforced concrete and stone construction, irrigation, electrocorrosion, leakage current and stray currents, demolition, restoration and protection, diagnosis, prognosis.
