CEN/TC 51/WG 6 - Definitions and terminology of cement

This document specifies cement with recycled concrete fines whose intended use is the preparation of concrete, mortar, grout, etc.

The general scope of the core product category rules (PCR) is given in EN 15804:2012+A2:2019, Clause 1.
This PCR is primarily intended for the creation of cradle-to-gate EPDs of cement and building lime.
In other respects, the scope is as in EN 15804:2012+A2:2019.

This document deals with Portland-composite cement CEM II/C-M, not covered by EN 197-1, and a different type of Composite cement CEM VI, also not covered by EN 197-1, whose intended use is the preparation of concrete, mortar, grout etc.
This document does not cover:
- common cement covered by EN 197-1;
- very low heat special cement covered by EN 14216;
- supersulfated cement covered by EN 15743;
- calcium aluminate cement covered by EN 14647;
- masonry cement covered by EN 413-1.

This European Standard defines and gives the specifications of six distinct very low heat special cement products 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 single strength class having a limited heat of hydration value. The definition also includes requirements the constituents have to meet and the mechanical, physical, chemical and heat of hydration requirements for these products. This European Standard also states the conformity criteria and the related rules. Necessary durability requirements are also given.
In addition to the specified requirements, an exchange of additional information between the cement producer and user can be helpful. The procedures for such an exchange are not within the scope of this European Standard but should be dealt with in accordance with national standards or regulations or can be agreed between the parties concerned.
NOTE 1   The word "cement" in this European Standard is used to refer to very low heat special cement unless otherwise indicated.
NOTE 2   The risk of early-age thermal cracking in concrete depends upon the properties and execution and is, therefore, also dependent on factors other than the heat of hydration of the cement.

This CEN Technical Report provides guidance for the procedure to be followed in order to support the European standardization of new cements that are not covered by an existing European Standard.
The term 'new cement' has been used in this document to describe its primary focus, however, this same guideline procedure may be used for other products to be standardized by CEN/TC 51.

This European Standard defines and gives the specifications of supersulfated cement and its constituents. The definition of supersulfated cement includes the proportions in which the constituents are to be combined to produce products in accordance with this standard. The definition also includes requirements the constituents have to meet and the mechanical, physical, chemical including heat of hydration requirements. This standard also states the conformity criteria and the related rules.
NOTE 1   In addition to the specified requirements, an exchange of additional information between the cement manufacturer and user may 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 may be agreed between the parties concerned.
NOTE 2     The word "cement" in this standard is used to refer only to supersulfated cement unless otherwise specified.

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.
This European Standard does not cover:
-   very low heat special cement covered by EN 14216;
-   supersulfated cement covered by EN 15743;
-   calcium aluminate cement covered by EN 14647;
masonry cement covered by EN 413-1.

This European Standard applies to Hydraulic binder for non-structural applications in construction used as binder for preparation of mortar for masonry, rendering and plastering and other non structural construction products.
This European Standard specifies the definition and composition of Hydraulic binder for non-structural applications (HB). It includes physical, mechanical and chemical requirements and defines strength classes. EN 15368 also states the conformity criteria and the related rules. Necessary durability requirements are also given.
NOTE   For normal applications the information given in this standard, and in the masonry specifications, EN 998-1 and EN 998-2, is generally sufficient. However, in special cases, an exchange of additional information between the producer and user can be helpful. The details of such an exchange are not within the scope of this standard but should be dealt with in accordance with national standards or other regulations or can be agreed between the parties concerned.
Terms of delivery or other contractual conditions, normally included in documents exchanged between the supplier and the purchaser of Hydraulic binder for non-structural applications, are outside the scope of this European Standard.

This European Standardt gives a general definition of calcium aluminate cement and its composition. It includes requirements for the mechanical, physical and chemical properties and also states the conformity criteria and the related rules.
Calcium aluminate cement used as a constituent material of formulated mixes for specific applications (e.g. dry mixes) is outside the scope of this European Standard.
NOTE   Guidance for the correct use of calcium aluminate cement in concrete and mortars is given in Annex A.
