By applying amine to reinforced concrete, we have developed a new method that simultaneously promotes CO₂ fixation in the concrete and prevents corrosion of the reinforcement. The features of this method are that it can be widely applied to both newly constructed and existing buildings, and that it is expected to extend the service life of buildings through corrosion inhibition of reinforcement. This method contributes to the achievement of carbon neutrality by making effective use of the huge amount of concrete stock that has been constructed to date. This paper describes the mechanism of CO₂ fixation acceleration and corrosion inhibition based on the experimental results using specific alkanolamines.
