Influence on Concrete Properties Using Multiple Corrosion Inhibitior

Arun Prasath T. M. E.

Abstract: Integral inhibitors are in the form of liquids or solids that are batched and mixed with other concrete ingredients to prevent for new construction or repair work. This paper, is an experimental study dealing with the strength and corrosion resistance behaviour of various integral type of corrosion inhibitors namely calcium nitrite and sodium nitrate at dosage of 4 %, 5 % and 6 % by weight of cement in concrete. The effects of these inhibitors is evaluated using the mechanical properties such as compressive strength, spilt tensile strength and the optimum dosage of inhibitors are determined. In the case of nitrate based inhibitors, addition of 6 % calcium nitrate and 5 % sodium nitrate shows maximum strength and further increase in sodium nitrate dosage results in decrease in strength due to decrease in the degree of hydration. It indicates that the admixed inhibitor has no harmful effect on the concrete used. The higher strength in the admixed samples than in the sample cured in water depends on the chemical activity of the inhibitors. It could probably be due to the relative chemical reactions, hardening effect of the inhibitor with the concrete.
