ABSTRACT
ABSTRACT. There exist a high selection of non-ferrous fibres, which have been applied into fibre reinforced concretes (FRC). The fibres are either natural plant fibres or synthetic fibres. However the use in practice still is quite limited. The aim of the future development work will be to avoid the difficulties, which still exist regarding to the long term durability and some times also regarding to the mechanical properties of FRC. It is proposed to apply a systematic tayloring of FRC in order to meet the requirements, which arise in the use at each application area. The local requirements of users and the requirements of the whole environment are quite different in different parts of the world. Also the buildings own different types of parts: Both strong and long life parts like the bearing frames and soft shorter term parts like the infill. The non-ferrous FRC materials are specially suited for the soft parts, but can be applied as a part of hybride reinforcements also into the strong parts. The principle of tayloring of the materials and structures leads to a design process, where specially the durability design, environmental analysis and generally the service life assessment have an important role.
