1 Scope 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. 2 Normative references The following referenced documents are indispensable for the application of this document.

Supersulfated cement. The composition of supersulfated cement shall be in accordance with Table 1. NOTE The requirements for the composition refer to the sum of all main and additional constituents. The final cement should be understood as the main and additional constituents plus the necessary additives. SIST EN 15743:2010+A1:2015

Three classes of standard strength are included: class 32,5, class 42,5 and class 52,5 (see Table 2). 7.1.2 Early strength The early strength of supersulfated cement is the compressive strength determined in accordance with EN 196-1 at either two days or seven days and shall conform to the requirements in Table 2. Two classes of early strength are included for each class of standard strength, a class with low early strength, indicated by L and a class with ordinary early strength, indicated by N (see Table 2).
