Corrosion Protection of Reinforced Steel in Concrete

The blast furnace slag is a secondary product resulting from the steel industry and produced in huge amounts every year. Therefore, the use of these wastes in any industry saves money and preserves the environment. The present work aims to study the physico-mechanical properties of different cement paste. Also, the effect of cement types on the electrochemical behavior of reinforcing steel in different aqueous solutions.

Also, the effect of cement types on the electrochemical behavior of reinforcing steel in different aggressive media. In addition, mineral additive Nanosilica was added to improve the properties of the cement pastes. Prof. Dr. Amal S. I. Ahmed, Prof. Dr. Wafaa A.Ghanem, Ass. Prof. Azza E. El-Shenawy, Ass.
