Shape of corrosion-induced cracks in recycled aggregate concrete. Of marine reinforced concrete with steel corrosion and cover cracking controlling the stage of corrosion initiation induced by chloride ion. Amongst others corrosion-induced cracking is the most prevalent damage . Distribution of the corrosion layer at the steel-concrete interface is established by . Chloride-induced corrosion rate (icorr) prediction models for RC structures in the marine tidal zone that incorporate the influence of crack width (wcr), cover. Bond behaviour of normal/recycled aggregate concrete and corroded steel bars. Steel corrosion reduces the strength and bond of the reinforcement and the oxides formed .. I want to simulate the cracking behavior of concrete as a result of progressivecorrosion of steel. Corrosion-induced cracking occurs when the embedded steel rebar starts to corrode and the resulting corrosion products push against the concrete. The paper presents a new analytical model to study the evolution of radialcracking around a corroding steel reinforcement bar embedded in concrete. 2.1 Two-phase FEM based corrosion model.
