Self Compacting Concrete (SCC) is the only choice in construction industry because of its easy movement in highly congested reinforcement in the structural members without segregation and bleeding. Use of SCC is increasing day by day because of its technical advantages over Normally Vibrated Concrete (NVC) in different parameters like self consolidation, smooth finishing and labour reduction. Corrosion is one of the important factors influencing strength, durability and service life of Reinforced Concrete (RC)
structures. This paper studies the mechanical properties of NVC and SCC of M30 grade and the extent of corrosion in NVC and SCC beams experimentally after 28 days when they are immersed in Nacl & Mg solutions to provide alkaline environment. The test results revealed that SCC shows better strength in compression and tension than that of NVC
