On Some Problems of Security Technology and Durabilityof Buildings and Engineering Infrastructure
On the basis of the classical and latest theoretical and experimental studies, efficient recommendations on preventing the destruction of building structures due to corrosion are proposed.The mathematical simulation of the corrosion mass-transfer in the course of corrosion of cement concretes of the first type, which occurs in the concrete under the impact ofwater with low hardness when components of the cement stone are dissolved, washed away, and carried away by the moving aqueous media, has been carried out. The boundary problemof mass conductivity in dimensional and non-dimensional variables is presented. The final solution of the problem using the method of Laplace at low values of Fourier number formass exchange, as well as its practical application when inspecting the building structures of the water reservoir for fire fighting is presented.
