A Review of Corrosion and Protection of Steel in Concrete

Corrosion of reinforcement is one of the major durability challenges which leads to a reduction in the design life of reinforced concrete. Due to an increasing demand for longer service lives of infrastructure (typically 100-120 years) and the high cost involved in building and maintaining it, the repair of concrete structures has become extremely important. This paper discusses mechanism of

What is Concrete Corrosion? - Definition from Corrosionpedia

Concrete corrosion is the chemical, colloidal or physicochemical deterioration and disintegration of solid concrete components and structures, due to attack by reactive liquids and gases. This type of corrosion causes widespread damage to critical sewage pipelines, bridges and other critical assets made of concrete.

Corrosion in Concrete Reinforcement & Repairs to Corroded

The basic problem in Reinforced concrete structures is the corrosion of steel reinforcement. The main cause of this corrosion is intrusion of water inside the RC structures. The corrosion of steel reinforcement can be judged by peculiar cracking of concrete structures. At last stage of corrosion, the steel reinforcement becomes exposed and the extent of corrosion

Probabilistic modeling of structural deterioration of

For existing reinforced concrete structures exposed to saline or marine conditions, there is an increasing engineering interest in their remaining safety and serviceability. A significant factor is the corrosion of steel reinforcement. At present there is little field experience and other data available. This limits the possibility for developing purely empirical models for strength and

Corrosion measurement and evaluation techniques of steel

This chapter reviews different techniques for evaluating and measuring the corrosion of steel in concrete. Since corrosion consists of electrochemical reactions at the interface between the metal (i.e., reinforcing steel) and an electrolyte solution (i.e., concrete pore solution), most of these measurement techniques are based on electrochemistry and electrochemical measurement methods.
