It is intended that this period will comprise a nominal nine month period during which any required changes to national regulations are to be made, followed by a further nominal twelve month period for the implementation of CE marking.

It has been chosen as the most common descriptor of the product, though other terms that have been used are set o

11、f non-UK National Standards for silica fume. UK-based operators who have previously used these standards might need to familiarize themselves with any changes in the requirements of this “harmonized” standard.Further information on the changes effected by the implementation of this standard can be o

27、1:2005+A1:2009EN 13263-1:2005+A1:2009 (E) 4 Introduction Silica fume consists of mainly spherical particles of amorphous silicon dioxide smaller than 106m and is highly pozzolanic. It is collected by filters as a by-product of the smelting process to produce silicon metal and ferro-silicon alloys. I
28、t can be supplied as collected from the filters (undensified), after treatment to increase its bulk density (densified), or as a slurry. Silica fume from more than one furnace, filter or intermediate storage silo will normally be blended in the production plant. Many years of research and practical
29、experience have demonstrated that silica fume which satisfies the requirements in this Part of this European Standard has highly pozzolanic properties, and may be used to produce concrete with improved properties in both the fresh and hardened states. Silica fume is normally used in combination with
30、 a plasticizer and/or superplasticizer. BS EN 13263-1:2005+A1:2009EN 13263-1:2005+A1:2009 (E) 5 1 Scope This European Standard applies to the silica fume which is a by-product of the smelting process used to produce silicon metal and ferro-silicon alloys. This part of EN 13263 gives requirements for
31、 chemical and physical properties for silica fume to be used as a type II addition in concrete conforming to EN 206-1, or in mortars, grouts and other mixes. This part of EN 13263 also states conformity criteria and related rules. EN 13263 does not give rules for the use of silica fume in concrete.
32、Some rules are given in EN 206-1. NOTE 1 Supplementary rules related to the use of silica fume in concrete may be given in non conflicting national standards for concrete. NOTE 2 EN 206-1 (5.2.5.1 in the 2000 edition) provides conditions for national acceptance of silica fumes coming from calcium si
33、licon alloys production or other silica fumes, not conforming completely to EN 13263, as type II additions for use in concrete. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.
