Control of corrosion destruction processes of building materials on the basis of mass transfer laws








The article considers some corrosion aspects of different types of cement concrete in aggressive environments. The possibility of using mathematical modeling to predict the durability of building materials is shown. The authors present a mathematical model based on mass-transfer equations that allow calculating the concentration fields of the portable «target» component, in accordance with the thickness of the concrete structure, determining the average value of concentration at an arbitrary point in time, and assessing the value of the concentrations of the «target» component in the liquid aggressive medium. A distinctive feature of the obtained mathematical model from the well-known models of corrosion of concrete is not the constancy of the equilibrium concentration on the surface of a solid, but its dependence on the concentration of the component in the liquid phase.
