The attack of aggressive agents, such as chloride, is known to jeopardize the durability of concrete structures as it triggers corrosion in steel bars. Thus, the use of seawater in concrete-mixing has remained prohibited despite its high accessibility. In this study, Calcium Nitrite solution is initially added to the seawater-mixed concrete. Using non-destructive methods, its effectiveness as a coating for steel bar in seawater-mixed mortar is investigated. The results showed a pronounced effect of the different concentrations of Calcium Nitrite on the potential, besides, a better effect was found in the steel bar coated specimen. |
