摘要
In the present paper a protective action of Na2PO3F from corrosion of steel concrete in carbonated environments is presented. The inhibitor effect has been followed using electrochemical techniques. Na2PO3F has been tested as a curative method penetrating from outside when the steel reinforcement is already corroding by carbonation of concrete cover. Results show that the product can reduce significantly an active corrosion through the use of drying and wetting cycles of the concrete cover with solutions having high concentration of Na2PO3F.
