DIN EN 16622:2016-02EN 16622:2015 (E) 5 Introduction Silica-calcium fume (SCF) according to this European Standard is a special type of silica fume containing

26、some calcium. It is collected by filters as a by-product of the carbothermal process to produce silica-calcium alloys. It is only supplied as a densified product. SCF from more than one furnace, filter or intermediate storage silo will normally be blended in the production plant. Many years of pract

27、ical experience, especially in France, have demonstrated that SCF which satisfies the requirements in this European Standard has both hydraulic and pozzolanic properties, and may be used to produce concrete with improved properties in both the fresh and hardened states. SCF is normally used in combi

28、nation with a plasticizer and/or superplasticizer. This European Standard is based on EN 13263-1 “Silica fume for concrete - Part 1: Definitions, requirements and conformity criteria”, with similar structure and requirements. The differences in the material properties is taken into account, for inst

29、ance that silica-calcium fume is partly hydraulic unlike silica fume. When it comes to conformity, this European Standard refers to EN 13263-2 “Silica fume for concrete - Part 2: Conformity evaluation”. DIN EN 16622:2016-02EN 16622:2015 (E) 6 1 Scope This European Standard applies to the silica-calc

30、ium fume (SCF) which is a by-product of the carbothermal process used to produce silica-calcium alloys. This European Standard gives requirements for chemical and physical properties for SCF to be used as a type II addition in concrete conforming to EN 206, or in mortars, grouts and other mixes. Thi

31、s European Standard also states conformity criteria and related rules. This European Standard does not give rules for the use of SCF in concrete. Some general rules for the use of type II additions are given in EN 206. NOTE Supplementary rules related to the use of SCF in concrete may be given in no

32、n-conflicting national standards for concrete. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
