The Effects of Sodium Nitrite on Corrosion Resistance of Steel Reinforcement in Concrete

Güray Kılınççeker *,Nida Yeşilyurt

Abstract

This study describes a laboratory investigation of the influence of 0.1 M nitrite ions on the corrosion of reinforcing steel and on the compressive strength of concrete. The effect of 0.1 M nitrite ions on the corrosion resistance of steel reinforced concrete was evaluated by electrochemical tests in distilled water, 3.5% NaCl and 3.5% NaCl + 0.1 M NaNO2 solutions for 90 days. In the presence of 0.1 M nitrite ions polarization resistance (Rp) values of reinforced concrete were higher than those without Sodium nitrite. AC impedance spectra revealed the similar results with Rp measurements. The compressive strength of concrete specimens containing 0.1 M nitrite ions was measured and an increase of 14.7-38.9% was observed.
