Résumé
Corrosion characteristics of reinforcement in modified high-alumina cement (HAC) containing a conversion-preventing additive (CPA) was studied. An investigation was carried out using ordinary portland cement, high-alumina cement, and modified high-alumina cement. Results includingcompressive strength, bond strength, porosity, CT permeability, and extent of steel bar corrosion are presented. The effect of a deicing salt, calcium chloride, on formation of hydrogarnet and strätlingite in HAC and modified HAC mortars is also reported. This work indicates that HAC mortar, after conversion, is unable to protect the reinforcement from corrosion in an environment containing chloride ions. Conversion-inhibited high-alumina cement has the capability of protecting the reinforcement fromcorrosion under severe test conditions due to its effective resistance to the penetration of chloride ions.
