A Review of Biological attack on Concrete and Steel to Assess its its Possible Impact On Mechanical Deterioration of Gravity Based Structure (CGBS) off shore Platforms

Abstract

Reza Javaherdashti

When it comes to reinforced concrete (RC) structures, the problem of Microbiologically Influenced Corrosion (MIC) of steel and Microbiologically Influenced Deterioration (MID) of concrete can have a joint disastrous effect on the integrity of the structure. MIC of steel (and other metals) has been the subject of many researches for many years, so have been the MID problems in sewage systems and wastewater treatment facilities. However, there are very few published materials to address MIC/MID scenarios in concrete gravity based (CGBS) platforms. This paper reviews some of the possible mechanisms that can be involved in MIC/MID events in such structures along with evaluating the feasibility of current countermeasures taken in practice.
