object - a flooded concrete, reinforced concrete and stone structures, which operate on DC electrified railways stations and destroyed; goal - development of ideas about the mechanism elektrokorrozii flooded concrete under a constant current to an electrically powered transport on the basis of ideas about electrosurface properties, phenomena, processes and interactions in dispersed systems and use these ideas to improve the durability of concrete, stone and concrete structures in harsh environments, techniques - analytical, physical, chemical, mathematical, statistical, novelty - to develop criteria for assessing the state of elektrokorrozionnogo watered concrete structures on the electrified sections of the DC path refined equations strength of cement stone, reflecting a decrease of elektrogeterogennyh contacts, establish the mechanism and developed physical and mathematical models of the external electric field on the phase composition of cement, the strength and non-pressure water permeability of concrete, to clarify the mechanism of dissolution portlandita in cement stone and removal of products of dissolution under the influence of a pulsating unidirectional dc electric field, the equations developed steady flow under the influence of electromigration force, the equation of equality of electromigration and capillary pressure developed schemes flow of leakage currents from the rails in the construction of buildings and removal of hydration products into the water, which contacts the concrete and the results - to develop a cement-water slurry and concretes with improved elektrokorrozionnoy resistance in difficult operating conditions, developed recommendations for the use of new high nedefitsitnyh and inexpensive materials and relatively simple technology of protection and restoration of buildings and structures of rail transport in difficult operating conditions, developed (in collaboration) and approved by regulatory documents specifications , technical guidance, recommendations, developed a method for determining elektrokorrozionnoy stability of protective coatings, developed physical and mathematical models elektrokorrozii possible to predict the actual longevity of structures, the scope of use - design, construction, reconstruction and rehabilitation of engineering structures and buildings on the railway transport of Ukraine and other countries.
