Concrete Structure Protection of Steel Reinforcement

The greatest threat to the durability of reinforced concrete structures is the reinforcement corrosion. The paper presents the importance of the concrete protective cover and the conditions causing the reinforcementcorrosion under the action of cklorides and carbonic acid. Processes of absorption, diffusion and flow i. e. of transport of media through concrete depend on the pore system and the amount of water in the pores. Physical laws describing the penetration of aggressive agents into concrete can serve as a basis for engineering calculations of reinforcement durability in the concrete as well as for the designing of the concrete cover.
