12. Infrastructure — Corrosion of reinforced concrete
Author of the chapter: Michael Raupach
Reinforced concrete is the worldwide mostly used building material for our infrastructure. It is flexible, robust and economic. While the compressive strength of concrete is quite high, the tensile strength is very limited. Therefore, usually steel reinforcement is used to create a powerful composite material. However, due to different mechanisms these reinforcements often corrode. Especially when chlorides are attacking the structures the corrosion rates can be very high and result in serious damages up to partial or complete collapses. Due to the increasing age of our infrastructure the costs for maintenance is also increasing. For the traffic infrastructure in industrial countries about 50% of the maintenance costs are directly related to corrosion. The costs for corrosion of reinforced...
