A number of countries, including Japan, Australia, France, Brazil etc., have developed standards for the local use of silica fume. Canada pioneered the development of standards: CAN/CSA A23.5-M86 Supplementary Cementitious Materials, was the first comprehensive national standard that also covered silica fume.
Standard Norge – the Norwegian body for standards – published NS 3045 in 1992, which it submitted to CEN (Comité Européen de Normalisation/European Committee for Standardization) for development into a European Standard.
Standards development for the European construction industry is governed by the Construction Products Directive (89/106/EEC) replaced in 2011 by the Regulation 305/2011 laying down harmonised conditions for the marketing of construction products: Regulation 305/2011
For silica fume, a Working Group (WG9) was established under the Committee for Concrete and Related Products (TC 104), the group that is responsible for EN 206: "Concrete - Part 1: Specification performance, production and conformity".
EN 13263 "Silica Fume in Concrete" was published in 2005 and supplemented in 2009 by the two additional documents outlined below.
Silica fume for concrete - Part 1: Definitions, requirements and conformity criteria:
Silica fume for concrete - Part 2: Conformity evaluation:
The mandatory physical and chemical requirements 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 are summarized in the table below. Part 1 of EN 13263 also specifies conformity criteria and related rules. Some rules for the use of silica fume in concrete 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 (184.108.40.206 in the 2000 edition) specifies the conditions for national acceptance of silica fumes coming from calcium silicon alloys production or other silica fumes that do not conform completely to EN 13263, as Type II additions for use in concrete.
Part 2 of EN 13263 specifies the scheme for the evaluation of conformity of silica fume to EN 13263-1, including certification of conformity by a certification body. This European Standard provides technical rules for production control by the manufacturer, including auto control testing of samples, and for the tasks of the certification body. It also provides rules for actions to be followed in the event of non-conformity and the procedure for the certification of conformity.
The American Society for Testing and Materials has also published the ASTM C1240 - 12 Standard Specification for Silica Fume Used in Cementitious Mixtures: ASTM C1240
Nearly 300 papers related to Silica Fume have been published by ASTM: ASTM papers on Silica Fume
