Objective

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