ABSTRACT
Several years ago a European Standard organization (CEN) was established to coordinate the production of European Technical Standards. One of these standards deals with shotcrete, or in the terminology of the European standard — “sprayed concrete”. The standard also covers steel fibre reinforcement, but not polymer or glass fibre reinforcement. Steel fibre reinforced sprayed concretes are classified not only according to compressive strength and environmental conditions as ordinary concretes are, but by residual strength classes combined with deformation classes determined from a particular bending test which does not appear to be useful for other type of fibre reinforcement.
