Makarenko O. Simulation modeling of сorrosion of concrete in aggressive environment of ore-preparation plants.

The dissertation on acquiring of a scientific degree of Cand.Tech.Sci. on a speciality 05.23.05 - Building materials and products. The Kharkov State Engineering University of Building and Architecture. Kharkiv. 2004. The thesis deals with development of a method of an estimation of concrete corrosion state of constructive members used in the aggressive environment, simulation modeling of the corrosion processes in concrete, development of recommendations on provision durability live service of constructions on the given operating period under the conditions, typical for ore-preparation plants. Methods of analytical investigation of processes of interaction of concrete of the constructive members exposed to aggressive influences are developed. Magnitudes of an index of a corrosion state of these concretes at different stages of interaction of concrete and a hostile environment are defined. Influence of limiting values of parameters which enter into an estimation of a corrosion condition on magnitude ofthe predicted period of preservation of protective properties by concrete is investigated. Keywords: concrete, ore-preparation production, corrosion of concrete, prediction of endurance of constructions, measure of a corrosion condition, parameters of the corrosion condition, elasticity, interchangeability of parameters.
