Development of ingibitor composition of corrosion for protection of steel armature

Аннотация

For over 150 years, reinforced concrete structures have been used in construction. A long-term study of the durability of reinforced concrete structures in various operating conditions shows that dangerous damages caused by the development of reinforcement corrosion, which pose a threat to public health, are often encountered. Corrosion of reinforcement is usually caused by exposure to reinforced concrete by atmospheric chemical factors caused by the presence of aggressive components in concrete, such as sulfates, carbonates, chlorides. Today in domestic practice there are over 100 different compositions for inhibiting the corrosion of reinforcing steel. The best results are achieved with the use of inhibitory additives to the cement of sodium and calcium nitrites.
