Title: Protection of Steel Reinforcing by the Passivating Effect of Lightweight Concrete

Abstract:Presents the results of an investigation into the corrosion of steel in lightweight concretes made with different types of lightweight aggregates. After many years of investigation of reinforced concrete made with lightweight aggregates, it was revealed that they can have satisfactory resistance to salt attack. Previously, it was believed that the greater permeability of some lightweight aggregates would not permit their use in reinforced lightweight concrete structures on an equal basis with normal weight concrete. The investigation performed on the corrosion of steel in concretes of different compositions, employing accelerated test methods as well as industrial experience, indicates that it is possible to use lightweight concrete for load-bearing and enclosure structures in urban and civil engineering applications.
