AcronymPrestress - GRC
Proposal titleInnovative Prestress Systems for G.R.CStrutural Elements
AbstractThe GRC precast structural elements have high durability as no steel is incorporated.
Unfortunately use this material prestress must be applied. The use of unbounded prestress
presents some technical problems related to steel relaxation and to the anchorage systems.
Besides that to obtain elements corrosion free prestress tendons must be made of non
metallic materials, namely fibre reinforced polymer (FRP) tendons, made of glass , aramid
or carbon fibres. The use of these materials in prestress presents technical difficulties
namely associated with their interaction and adherence with GRC. If these problems are
overcome then the precast industry has quitea new material with economical,
social/environment advantages and with a very high durability. This project as the aim of
developing new prestress systems to be applied in GRC structural elements,with the
emphasis in the use of FRP tendons. Solutions for the rope protection, adherence,
anchorage, prestress control and prestress behaviour along time will be analysed.
Prototypes of GRC element prestressed with the new systems will be built and tested.
