Abstract:
The tunnelling and maritime environments can provide extreme conditions for reinforced concrete. Exposure to aggressive saline water can be combined with design lives of 100 years or more. In recent years, traditional carbon steel reinforcement has been substituted by the use of steel fibres and, more recently, by synthetic fibres for sprayed concrete and precast items, such as tunnel segments. This paper describes some of the factors which have prompted the change from rebar to fibres and includes a detailed consideration of the specific durability design aspects of fibre reinforced concrete use within desalination facilities.
