22、andard, either by publication of an identical text or by endorsement, at the latest by January 2016, and conflicting national standards shall be withdrawn at the latest by April 2017.

Compared to the version EN 14216:2004 the following major changes have been included in this document: use of the terminology given by the Construction Products R
24、egulation (Regulation (EU) No 305/2011); a clause “Dangerous substances” has been added; the former Annex A (informative) “Water-soluble hexavalent chromium” has been deleted; Annex ZA has been revised in accordance with the Construction Products Regulation (Regulation (EU) No 305/2011). This docume
25、nt has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. For relationship with Regulation (EU) No. 305/2011, see informative Annex ZA, which is an integral part of this document. The various stages in the development of a European Standard
26、 for common cement, in response to the preliminary mandate given to CEN by the EC and the EFTA, are described in EN 197-1. It is indicated that, in view of the large numbers of different cements involved, it was considered necessary to separate the “common cements“, which are now covered by EN 197-1
27、, from special cements, i.e. those with special properties or those having hardening processes not mainly dependent on the hydration of calcium silicates. The low heat property for common cements is covered by EN 197-1. A need for control of heat development during hydration of concrete is referred
28、to in EN 206. Classification of cements with respect to heat of hydration is one method whereby heat development of concrete can be controlled. The purpose of this European Standard is therefore to specify the heat of hydration for very low heat special cements. Composition and other requirements ar
29、e those specified in EN 197-1 for common cements. Conformity criteria are additionally specified. The requirements in this European Standard are based on the results of tests on cement in accordance with EN 196-1, EN 196-2, EN 196-3, EN 196-5, EN 196-7, EN 196-8 and EN 196-9. The scheme for the eval
30、uation of conformity in EN 197-2 is applicable to very low heat special cements. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republ
31、ic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

32、 14216:2015-09EN 14216:2015 (E) 4 Introduction It is recognized that different cements have different properties and performance. Those performance tests now available (i.e. setting time, strength, soundness and heat of hydration) have been included in this European Standard. In addition, work is be
33、ing carried out by CEN/TC 51 to identify any additional tests which are needed to specify further performance characteristics of cement. Until further performance tests are available, it is highly recommended that the choice of cement, especially the type and/or strength class in relation to the req
34、uirements for durability depending on exposure class and type of construction in which it is incorporated, follows the appropriate standards and/or regulations for concrete valid in the place of use. DIN EN 14216:2015-09EN 14216:2015 (E) 5 1 Scope This European Standard defines and gives the specifi
35、cations 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 defini
36、tion 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
37、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 agr
38、eed 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
39、factors other than the heat of hydration of the cement. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

DIN EN 14216:2015-09EN 14216:2015 (E) 6 4 Very low heat special cement Very low heat special 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 a
44、nd which, after hardening, retains its strength and stability even under water. It has hydration reactions and processes identical to those of common cements (see EN 197-1) but through composition, fineness or reactivity of constituents the hydration process is slower. Very low heat special cement i
45、s particularly suitable for dams and other similar massive construction, where the dimensions of the structure have a low surface/volume ratio. In this case, the dispersion of heat, developed during the hydration of the cement, is very slow and therefore it is possible to have large increases in tem
46、perature. Thermal gradients then develop between internal and external zones of the concrete setting up internal stress which can be greater than the tensile strength of the concrete and lead to cracking and breakdown. These same properties make very low heat special cement unsuitable for use in rei
47、nforced, elevated, concrete structures, e.g. bridges or buildings. NOTE Low heat common cements or low heat low early strength blastfurnace cements conforming to EN 197-1 are suitable for dams and other similar massive construction, depending on the design of the concrete and method of construction.
48、 5 Constituents The constituents of very low heat special cements shall conform to the requirements of the constituents of common cements specified in EN 197-1. 6 Composition and notation The six products in the family of very low heat special cements, covered by this European Standard, and their notation are given in Table 1. They are grouped into three main cement types as follows: VLH III Blastfurnace cement; VLH IV Pozzolanic cement; VLH V Composite cement. The composition of each of the six products in the family of very
