Abstract: In modern construction concrete and steel are the important materials in RC Buildings. In that, steel plays a major role in strength and durability properties of the structures. The Chloride ion present in the concrete form a passive layer over the embedded steel in concrete causes breakdown. Corrosion of steel occurs due to chemical attack and environmental attack. Steel losses its strength due to corrosion and it needs to be protected. Geo-polymer concrete is a new alternative to conventional concrete. The engineering and construction industry has successfully engaged in challenge for consuming “Sustainable green and recycled products” in manufacture of concrete. In order to reduce the environmental problem related to disposal of Ground Granulated Blast Furnace Slag (GGBS) has potential to be used as concrete material. In this research paper, we deal with prediction of corrosion rate with various methods and also the mechanical properties of the GGBS based Geo-polymer Concrete.
