NOTE

  • In this group, the following terms or expressions are used with the meanings indicated:
    • "reinforcing" means increasing any physical strength characteristic of the end product, e.g. compressive or flexural strength;
    • "elements" includes relatively large bodies, e.g. steel bars, as well as relatively small discrete bodies of any form, e.g. glass fibres.
  • Discrete reinforcing elements, which are small compared with the reinforced building element, only characterised by their composition are classified in C04B, e.g. steel fibres C04B 14/48, plastic elements with a shape other than granular or fibrous C04B 16/12
