Scope

This European Standard specifies requirements for the properties of fly ash for use as a type II addition for preparation of concrete, mortar and grout, including in particular cast-in-situ or prefabricated structural concrete conforming to prEN 206-1. Fly ash for use in the manufacture of cements according to prEN 197-1 is outside the scope of this standard. Provisions governing the practical application of fly ash in the production of concrete, i. e. requirements concerning composition, mixing, placing, curing etc. of concrete containing fly ash are not part of this standard. As regards such provisions, reference should be made to other European or national standards for concrete.
