Influence ofw/c ratio on rate of chloride induced corrosion of steel reinforcement and its dependence on ambient temperature

  • V. Živica


The permeability of the embedding cement material for the rate of chloride induced corrosion when the ambient temperature is increased has found a dominant position. The importance of the given permeability in the process is based on the fact that it represents a factor conditioning the possibility of the escaping of the unambiguous reaction partners, oxygen and water vapour, from the system embedding cement material— steel, as the ambient temperature is increased. The resulting effect is a slowing down of the corrosion rate when the w/c ratio over the value 0.6 and the ambient temperature over the value 40†C are increased.

Due to the similarity of the chemism of the corrosion process of steel reinforcement, independent of the action of aggressive species, the found relationships are generally valid, e.g. for the corrosion due to carbonation.
