CEN/TC 104/WG 9 - Silica fume for concrete

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.
NOTE   Supplementary rules related to the use of SCF in concrete may be given in non-conflicting national standards for concrete.

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 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. 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 silicon alloys production or other silica fumes, not conforming completely to EN 13263, as type II additions for use in concrete.

This part 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 autocontrol 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.
