Cement -- Composition, specifications and conformity criteria for low early strength blastfurnace cements
This prEN 197-4 defines and gives the specifications of 3 distinct low early strength blastfurnace 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 three strength classes.
The definition also includes requirements the constituents have to meet and the mechanical, physical, chemical, including where appropriate, heat of hydration, requirements and strength classes.
This prEN 197-4 also states the conformity criteria and the related rules. Necessary durability requirements are also given.
NOTE 1 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 prEN 197-4 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 this prEN 197-4 is used to refer only to low early strength blastfurnace cements unless otherwise indicated.
