Microbiologically influenced Corrosion (MIC) of construction materials: steel and concrete

Microbe assisted corrosion/detrioration of steel and concrete

Bridges and concrete structures are vulnerable to corrosion particularly microbiologically influenced corrosion (MIC) and/or microbiologically influenced deterioration (MID). MID can affect mechanical integrity of concrete to be lowered in the same way that MIC does to steel where both would lead into premature failure of steel bridges and concrete structures.

Microbiologically influenced corrosion (MIC) via the impact of some micro-organisms such as - but not limited to - bacteria can affect the mechanical integrity of steel structures including steel bridges. The corrosive role of these micro-organisms could be via lowering local pH or establishment of electrochemical cells.   

Microbiologically influenced deterioration (MID) can affect a wide range of non-metals including concrete structures, for instance concrete parts of bridges and wastewater treatment facilities. While mechanisms such as weathering and its effect on concrete are known, less is known about MID-assisted atmospheric deterioration of concrete for instance.

Recognize,  evaluate and prevent MIC and MID

After completing this course you:

  • can assess and differentiate various corrosion mechanisms as per intended structure
  • are able to evaluate MIC/MID and the ways by which they can be treated and/or prevented
  • know the pros and cons of in-market methods to recognize and treat corrosion in general and MIC/MID in particular
  • are able to design better maintenance and operation schedules
  • can categorise the loss and control/prevention of remote-looking accidents or disasters
     

Intended for
The course is intended for civil engineers, structural engineers, technical design engineers, corrosion engineers, technical inspectors, operation and maintenance professionals, industrial research and development (R&D) professionals, water specialists working with underground pipelines, infrastructure professionals at municipalities, microbiologists and academic researchers.
