MODELLING OF CORROSION PROTECTION FOR REINFORCED CONCRETE STRUCTURES WITH SURFACE COATINGS/GELŽBETONINIŲ KONSTRUKCIJŲ SU PAVIRŠINĖMIS DANGOMIS KOROZINĖS APSAUGOS MODELIAVIMAS

Abstract Corrosion is a serious problem for the durability of reinforced concrete structures. These structures need to be protected from corrosion in a variety of exposure conditions ranging from atmospheric to continuous immersion in water or chemicals. One of the ways to protect reinforced concrete structures from corrosion is to use protective coatings. The surface barriers of non‐degradable materials are able to slow down considerably the rate of deterioration of concrete structures and to overcome most durability problems associated with external attack. Design of durability of concrete structures with protective coatings needs to be established. In this paper a general framework for service life prediction and reliability evaluation of anticorrosion protective system (CPS), which is represented by protective surface barrier, concrete cover, and steel reinforcement itself of reinforced concrete structures, is presented. This approach is based on a reasonable understanding of the main degradation proc...
