Effect of Air Entraining Admixture on Corrosion of Reinforced Concrete

Reinforced concrete structures affected by the attack, sulfates, carbonates and chlorides. The most important factor in the corrosion of reinforced concrete structures is due to chloride attack and prevent corrosion of the reinforcing steel is done by reducing chlorides through the concrete appropriate thickness of reinforced concrete which also controls the permeability of concrete coating layer occurs. So in this study, 5 mix with various of air entraining admixture on cylindrical sample along with 15 mm reinforced bar has been defined for preparation test samples which is aimed to determine corrosion and water absorption properties. Results shows that air entraining have a huge impact on water absorption and electrical resistivity of concrete. (C) 2016 The Authors. Published by Elsevier Ltd.
