CEMENT

Part 1: Composition, specifications and conformity criteria for common cements

1 1 SCOPE

This European Standard defines and gives the specifications of 27 distinct common cements, 7 sulfate resisting common cements as well as 3 distinct low early strength blast furnace cements and 2 sulfate resisting low early strength blast furnace cements and their constituents. The definition of each cement includes the proportions in which the constituents are to be combined to produce these distinct products in a range of nine strength classes. The definition also includes requirements which the constituents have to meet. It also includes mechanical, physical, and chemical requirements. Furthermore, this standard states the conformity criteria and the related rules. Necessary durability requirements are also given.
In addition to those sulfate resisting cements defined in the present document, other cements conforming either to this standard or to other standards, European or national, have been nationally demonstrated to have sulfate resisting properties. These cements which are listed in Annex A, are considered by different CEN Member countries as sulfate resisting within the limits of their territory.
NOTE 1 In addition to the specified requirements, an exchange of additional information between the cement manufacturer and user can be helpful. The procedures for such an exchange are not within the scope of this standard but should be dealt with in accordance with national standards or regulations or can be agreed between the parties concerned.
NOTE 2 The word "cement" in EN 197-1 is used to refer only to common cements unless otherwise specified.

- supersulfated cement covered by EN 15743;
- calcium aluminate cement covered by EN 14647;
- masonry cement covered by EN 413-1.

3 TERMS AND DEFINITIONS

For the purposes of this document, the following terms and definitions apply.
3.1 reactive calcium oxide (CaO)
fraction of the calcium oxide which, under normal hardening conditions, can form calcium silicate hydrates or calcium aluminate hydrates
NOTE To evaluate this fraction, the total calcium oxide content (see EN 196-2) is reduced by the fraction corresponding to calcium carbonate (CaCO 3 ), based on the measured carbon dioxide (CO 2 ) content (see EN 196-2), and the fraction corresponding to calcium sulfate (CaSO 4 ), based on the measured sulfate (SO 3 ) content (see EN 196-2) after subtraction of the SO 3 taken up by alkalis.
3.2 reactive silicon dioxide (SiO 2 )
fraction of the silicon dioxide which is soluble after treatment with hydrochloric acid (HCI) and with boiling potassium hydroxide (KOH) solution
NOTE The quantity of reactive silicon dioxide is determined by subtracting from the total silicon dioxide content (see EN 196-2) the fraction contained in the residue insoluble in hydrochloric acid and potassium hydroxide (see EN 196-2), both on a dry basis.
3.3 main constituent
specially selected inorganic material in a proportion exceeding 5 % by mass related to the sum of all main and minor additional constituents
3.4 minor additional constituent
specially selected inorganic material used in a proportion not exceeding a total of 5 % by mass related to the sum of all main and minor additional constituents
3.5 type of common cement
one of the 27 products (see Table 1) in the family of common cements
3.6 strength class of cement
class of compressive strength

3.8 control period
period of production and dispatch identified for the evaluation of the autocontrol test results EN 197-1:2011 (E)
3.9 characteristic value
value of a required property outside of which lies a specified percentage, the percentile P K , of all the values of the population
3.10 specified characteristic value
characteristic value of a mechanical, physical or chemical 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
3.11 single result limit value
value of a mechanical, physical or chemical 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
3.12 allowable probability of acceptance CR
for a given sampling plan, allowed probability of acceptance of cement with a characteristic value outside the specified characteristic value
3.13 sampling plan
specific plan which states the (statistical) sample size(s) to be used, the percentile P K and the allowable probability of acceptance CR
3.14 spot sample
sample which is taken at the same time and from one and the same place, relating to the intended tests, and which can be obtained by combining one or more immediately consecutive increments
NOTE See EN 196-7.

4 CEMENT

Cement is a hydraulic binder, i.e. a finely ground inorganic material which, when mixed with water, forms a paste which sets and hardens by means of hydration reactions and processes and which, after hardening, retains its strength and stability even under water.
