Objective
The project aims at: 1 improving thc corrosion resistancc of the galvanized steel rebar in very alkaline environments such as those occurring in concrete, by means of a new organic-type surface passivation treatment; 2. decreasing the interfacial steel/zinc-coating brittleness which causes craeks and/or flaking of the coating of bended rebars, which are sites of preferential corrosion attack; 3. suggesting the best chemical composition of the steel rebar in order to minimize the steel/coating brittle interphase. The objectives shall be reached varying the surface properties of zinc by surface conversion and the chemistry of the steel/coating interface. The effects of alloying elements of the steel rebar on the thiekness, constitution, and morphology of the galvanized coating will be studied on the attempt to establish the effect of these changes on the adherence of the coatings as assessed by a simple bent test. Aiming at extending the chemical stability of gavanized bars in very alkaline environments above pH 13.2 tests will be made using water-born organic passivating solutions chromium (VI)-free, in which the organic vehicle will be carefully chosen. In order to simplify the passivating operation and reduce application costs, spray application of the solution shall take into account, immediately after hot-dipping, allowing cooling within the range of temperatures useful for curing the organic passivating film, thus exploiting the residual heat of the galvanized bars. As an alternative, tests will also be made for the application of organic passivation on galvanized bars just before field construction of concrete structures.
