СУЧАСНІ МЕТОДИ ЗАХИСТУ АРМАТУРИ ЗАЛІЗОБЕТОННИХ КОНСТРУКЦІЙ ВІД КОРОЗІЇ

Abstract

Corrosion protection of reinforcement in concrete structures is a prerequisite for increasing the service life of building structures. Various protection methods are used In practice to reduce corrosion of reinforcing steel, for example: patch repair, protective coatings, concrete additives, etc. Methods of cathodic protection of reinforced concrete structures, such as the superimposed current method, as well as the more modern method using consumable "sacrificial" anodes, are increasingly
being used as an alternative. The latter method can be proposed as the most effective tool for corrosion prevention.
At the same time, due to the simplicity and widespread use of traditional anti-corrosion strategies, cathodic protection
with a "sacrificial" anode is still not a popular way to protect concrete. A critical review of the methods common at construction sites used to combat corrosion of reinforcement of concrete structures is given. Also the main methods of cathodic protection, principle of operation and main advantages are given.
