Durability-based design, monitoring, and repair of reinforced concrete structures: A review

Corrosion of reinforcement, due to severe micro-environments and/or poor co ncrete quality, has caused serious damage to concrete structures. To avoid future damage and repeated damage after repair, new approaches to durabilit y design, monitoring, and repair of concrete structures, based on the mecha nisms governing the deterioration processes, are presented. Like the proced ure for load design, design for durability should be performance-based, tak ing into account the probabilistic nature of the processes and material pro perties involved. Testing of the durability-related quality parameters and monitoring the structures during use must be integral parts of the design a nd maintenance procedures for concrete structures.
