Precast concrete products. Wall elements Ingestion-build-135476 enabling the prevention of nitrogen1 Scope This European Standard applies to prefabricated walls, made of normal weight or lightweight concrete with dense structure. Also fibre reinforced concrete (steel, polymer or other fibres covered by European Standards) may be used. These wall elements may have external wall functions (see 3. 11) or not, have facing functions (see 3. 12) or not or have a combination of these functions. External wall functions could be: thermal insulation (see 3.
