EN 197-3 defines and gives the specification of 27 distinct low heat common 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 range of six strength classes and three heat of hydration classes. The definition also includes requirements the constituents have to meet and the mechanical, physical and chemical requirements of the 27 products, strength classes and heat of hydration classes. EN 197-3 also states the conformity criteria and the related rules. Necessary durability requirements are also given. The risk of early-age thermal cracking in concrete depends upon the properties and execution and is, therefore, also dependant on factors other than the heat of hydration of the cement. Therefore, advice on the use of low heat common cements is included in informative annex B.
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 EN 197-3 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 EN 197-3 is used to refer only to low heat common cements unless otherwise indicated.
