This paper presents an overview of research results and applying of Dimethl ethanolamine inhibitor (DMAE) to limit the corrosion of constructional steel in saline sand concrete for sustainable building material purpose. In this study,06 series of concrete samples were prepared with sanline sandof Dau resort, Hai Phong, Vietnam was used as fine aggegate. A CB300-V D10 bars (TCVN 1651-2:2018) was used for electrodes for corrosion testing. Electrochemical analyzes by corrosion potential of the samples were carried out in a 3% NaCl solution with a sample immersion time of 60, 90, 140 and 300days. Experimental results show that the corrosion ability of the samples were significantly reduced when using that inhibitors.

Keywords : Corrosion of steel, Corrosion potential,organic inhibitor, Saline sand, Sustainable building material.
