This SS EN 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 SS EN 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 SS EN 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 SS EN 197-4 is used to refer only to low early strength blastfurnace
cements unless otherwise indicated.
