THE SIMULATION OF CORROSION DEGRADATION OF CONCRETE SPECIMEN IN STATIONARY HEAT AND MOISTURE CONDITIONS

This paper is focused on the problem of forecasting damage in reinforced concrete specimens as the consequence of chloride corrosion. The performed numerical calculations included time necessary for filling empty pore space and tightening corrosion products in the interfacial transition zone (ITZ) . In those calculations we assumed the formation of distortional strains in the ITZ layer caused by mass increase of corrosion products dependent on corrosion current intensity.
