Service Life Prediction And Choice Of Repair Strategy For Rc Structures
Published online by Cambridge University Press: 10 February 2011
Abstract
The accumulating damage to concrete structures during the last years has led to an increasing need for repair work.
The need for concrete repairs is not likely to change in the future, not until all old concrete structures have been repaired or rehabilitated through preventive maintenance.
Both repair and preventive maintenance of a concrete structure require economic investment, not only at present, but also in the future. A repair does not last forever and preventive measures (e.g. surface treatment) require regular maintenance. Society does not have unlimited resources for the repair and maintenance of concrete structures. Consequently, there is a need for optimization of the resources, i.e. using few resources in the best way at the right time.
It is therefore necessary to base the repair/maintenance on technical and (in particular) economic evaluations.
The following describes a model for evaluation of the technical and economic need for repair/maintenance of concrete structures.
