MATHEMATICAL MODELING OF DIFFUSION PROCESSES OF MASS TRANSFER OF «FREE CALCIUM HYDROXIDE» DURING CORROSION OF CEMENT CONCRETES
Main Article Content
Abstract
The paper presents a mathematical model of mass transfer in the processes of corrosion of the first type of cement concrete at the level of phenomenological equations for a closed reservoir-liquid system. A step-by-step transition to the recording of the boundary value mass conduction problem in dimensionless coordinates is shown. The solutions of the boundary value mass conduction problem for the region of large and small values of Fourier numbers are obtained.
