1.Introduction. Steel corrosion is the leading cause of failures of the concrete structure in service. Generally, passive films form on the steel surface in a Portland cement based concrete in high pH environments (12.5–14.0) .However, this passive film becomes unstable and even disintegrated at reduced alkaline levels (with pH value below 10) .As a neutralization reaction, carbonation of ...
