Task Group 8.1 is preparing a technical report on the subject of the requirements for a model specification for repairs and interventions with the goal of achieving publication as an fib bulletin. Consideration will be given as to whether this work should later be taken forward as a future Guide to Good Practice.
A first draft report is under development. It has been decided to further develop the approach employed in a Norwegian document containing model technical specifications for a number of rehabilitation methods and align them to the Eurocode convention. In so doing it is envisaged that this report will deliver a model technical specification for a range of rehabilitation methods, each underpinned by their principles. Topics and techniques being considered for inclusion include: Concrete removal, concrete reinstatement, patch repair; surface treatments and coating; cathodic protection; chloride extraction; realkalisation; crack sealing; physical protection / barriers; cladding; inhibitors; electro–osmosis; sacrificial anode (in patch repair); strength; external reinforcement; jacketing; external pre-stressing and replacement and reconstruction of elements. These topics will be preceded by chapters covering the investigation of defective concrete from inspection and testing to monitoring.
