DIN EN 450-1:2012-10 EN 450-1:2012 (E) 4 Introduction The use of coal for electricity production results in the generation of large quantities of fly ash. Different types of coal and the type of boiler used in
27、this process produce different fly ashes, such as siliceous, silico-calcareous, or calcareous fly ashes with pozzolanic and/or latent hydraulic properties. All these types of fly ash are used in concrete production in some European countries, based on national experience and tradition. Before use, f
28、ly ash may be subject to processing, for example by classification, selection, sieving, drying, blending, grinding or carbon reduction, to optimize its fineness, reduce its water demand or to improve other properties. Such processed fly ashes may conform to this document to which reference is made i
29、n such case. If they are out of the scope of this document, their suitability for use as Type II additions in concrete according to EN 206-1 may also be established from national standards or provisions or European Technical Approvals valid in the place of use of the concrete and which refer specifi
30、cally to the use of the addition in concrete conforming to EN 206-1. When using fly ashes conforming to this document, it should be noted that, apart from the effect from the pozzolanicity of the fly ash, certain properties of fresh and hardened concrete may be affected. Where relevant, such effects
31、 need to be considered in concrete mix design (see EN 206-1). DIN EN 450-1:2012-10 EN 450-1:2012 (E) 5 1 Scope This European Standard 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 a
32、ddition for production of 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 Clause 4 is outside the scope of this European Standard.
33、 It is beyond the scope of this European Standard 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. Regarding such provisions, reference should be
34、made to other European or national standards for concrete, such as EN 206-1. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
