Abstract:
The corrosion resistance of reinforced concrete, containing fly ash and calcium nitrite-based corrosion inhibitor, under sea water attack was studied in this research. Aggressive and normal construction conditions were simulated. Test results indicate that the use of calcium nitrite-based corrosion inhibitor is an effective way to protect reinforcing steel from corrosion in aggressive environments. No serious detrimental effect was found for the corrosion inhibitor on concrete properties. Replacement of 20% cement by fly ash gives no apparent improvement in preventing the corrosion of steel in sea water exposure.
