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, where appropriate, 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 Supersulfated cement should not be used in combination with any other cement because of its high sulfate content. NOTE 3 The word "cement" in this Standard is used to refer only to supersulfated cements unless otherwise specified.
