Workability of the green concrete, compaction of concrete and cover depths play very important role to avoid corrosion of the steel reinforcement, also both the steel coating and steel diameters have its consideration effect to protect the steel reinforcement in structures. In this work twenty four specimens were cast, these were prisms 15 X 15 X 75 cm. Half of the specimens had steel reinforcements with diameter 14 mm and different covers 15 mm, 20mm and 30mm, while the second half had steel reinforcements the same cover 20 mm but with different steel diameters 10 mm, 12 mm and 14 mm, concretes for all specimens were mixed with different percentage of salt in mix water and water cement ratio (w/c= 0.35). Some specimens steel reinforcements were painted by primer (Sika Top Armatic – 110) and special additive (Sika viscocerte – 5400 salf concrete compaction S.C.C.) was added to improve the workability and compaction of the concrete mix.. The reinforcing steel had been connected to an electric circuit to accelerate corrosion process; the corrosion potential was being measured different on these specimens by (CSE) Half-Cell device.
