Corrosion of Concrete Structures with Consideration of the Filtration Moisture Transfer
Abstract: It has been made a mathematical model of the processes of corrosion of concrete marine structures based on consideration of the totality of the physical and chemical processes in the pore space of concrete. The model takes into account chemical processes that result in the accumulation in the concrete of sulfate and the formation of the films. On the basis of chemical and physical processes it has been solved the Stefan problem with moving boundary, which is reduced to the two-dimensional problem of the binding of aggressive substances in the liquid phase at the moving boundary. The proposed mathematical model can be used to improve the methods of conducting experimental studies, and further engineering methods of prediction of durability of structures operating in sea water.
Keywords: concrete, corrosion, mathematical model, aggressive environment.
