NOTE 2 Other names used for silica fume are condensed silica fume and microsilica. 3.25 silica fume slurry homogeneous, pH regulated liquid suspension of silica fume in water, typically with a dry content of 50 % by mass, corresponding to about 700 kg of silica fume per m³ of slurry 3.26 single result limit value value of a chemical or physical property which for any single test result – in the case of an upper limit is not to be exceeded or in the case of a lower limit is, as a minimum, to be reached 3.27 specified characteristic value characteristic value of a chemical or physical property which in the case of an upper limit is not to be exceeded or in the case of a lower limit is, as a minimum, to be reached NOTE Conformity with the specified characteristic values in this part of EN 13263 is verified by the methods in 7.2. 3.28 spot sample sample taken at the same time and from one and the same place, relating to the intended tests. It can be obtained by combining one or more immediately consecutive increments [EN 196-7:1989] 3.29 test technical operation that consists of the determination of a characteristic of a product according to a specified procedure [Adapted from EN 45020:1998] 3.30 test cement selected brand of Portland cement of type CEM I, strength class 42,5 N or higher, conforming to EN 197-1 to be used for carrying out the tests needed to evaluate conformity to the requirement of 5.3.3 in this part of EN 13263 Test cement is selected by the silica fume manufacturer and is further characterized by its fineness and contents of tricalcium aluminate and alkalis as follows:  Fineness:
300 m2/kg to 400 m2/kg when determined in accordance with EN 196-6;  Tricalcium aluminate:
8 % to 12 % when determined in accordance with EN 196-2;  Alkalis (Na2O eqv):
0,6 % to 1,2 % when determined in accordance with EN 196-2.

5.3.2 Dry mass content in slurry The dry mass content shall not deviate from the value declared by the supplier by more than ± 2 % by mass of the slurry when determined by drying a representative sample of at least 5 g of slurry in a well ventilated oven at (105 ± 5) °C to constant mass. Constant mass is considered to be reached when successive weighings at least 1 hour apart during drying at (105 ± 5) °C do not differ by more than 0,2 %. 5.3.3 Activity index The activity index is determined as the ratio (in percent) of the compressive strength of standard mortar bars, prepared with 90 % test cement plus 10 % silica fume per mass of total binder, to the compressive strength of standard mortar bars prepared with 100 % test cement, when tested at the same age. Preparation of standard mortar bars and determination of the compressive strength shall be carried out in accordance with the method described in EN 196-1. The mortar containing silica fume shall be mixed with an amount of superplasticizer (conforming to EN 934-2) so that the mortar has a consistency equivalent to the reference mortar when tested by the flow table method given in EN 413-2. The activity index shall be at least 100 % when tested at a mortar age of 28 days. NOTE 1 The result of the activity index tests gives no direct information on the strength contribution of silica fume in concrete, nor is the use of silica fume limited to mixing ratio used in these
