Background: European standards for concrete
Table 1 provides an overview of the relevant European standards pertaining to the use of aggregates for structural concrete. In the centre are the EN 206 for concrete and EN 12620 for aggregates for concrete.
EN 206 provides information concerning the specification, performance, production and conformity of concrete. It is amended on a national level, with associated standards and guidelines. EN 206-1 applies for structural concrete in situ (ready mixed), for precast structures and structural precast products for buildings and civil engineering works.
EN 12620 specifies the properties of normal weight (≥ 2 t/m³) aggregates and filler aggregates for use of concrete in accordance with EN 206. It covers aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these. Thus, it also applies to industrial by-products like IBAA.
