Resumen:
This document specifies requirements for the chemical and physical properties as well as quality control procedures for siliceous fly ash, as defined in 3.2, for use as a type II addition for production of concrete, including in particular cast-in-situ or prefabricated structural concrete conforming to EN 206-1. Fly ash according to this document may also be used in mortars and grouts. Fly ash produced with other types or higher percentages of co-combustion materials than those provided for in 4 is outside the scope of this document. It is, however, beyond the scope of this document to specify 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. As regards such provisions, reference should be made to other European or national standards for concrete, such as EN 206-1.
