DIN EN 16622:2016-02

This European Standard applies to the silica-calcium 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. This 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. Supplementary rules related to the use of SCF in concrete may be given in non-conflicting national standards for concrete.
