This document applies to hydraulic binder for non-structural applications in construction used as binder for preparation of mortar for masonry, rendering and plastering and other non-structural construction products.

This document specifies the definition and composition of hydraulic binder for non-structural applications (HB). It includes physical, mechanical and chemical requirements and defines strength classes. EN 15368 also states the conformity criteria and the related rules. Necessary durability requirements are also given.

For normal applications the information given in this document, and in the masonry specifications, EN 998‑1 and EN 998‑2, is generally sufficient. However, in special cases, an exchange of additional information between the producer and user can be helpful. The details of such an exchange are not within the scope of this document but can be dealt with in accordance with national standards or other regulations or can be agreed between the parties concerned.

Terms of delivery or other contractual conditions, normally included in documents exchanged between the supplier and the purchaser of hydraulic binder for non-structural applications, are outside the scope of this document.

This document defines and gives the specifications of 39 distinct common cements, 7 sulfate resisting common cements as well as 3 distinct low early strength blast furnace cements and 2 sulfate resisting low early strength blast furnace cements 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 nine strength classes. The definition also includes requirements which the constituents have to meet. It also includes mechanical, physical, and chemical requirements. Furthermore, this standard states the conformity criteria and the related rules. Necessary durability requirements are also given.

In addition to those sulfate resisting cements defined in the present document, other cements conforming either to this standard or to other standards, European or national, have been nationally demonstrated to have sulfate resisting properties. These cements which are listed in Annex A, are considered by different CEN Member countries as sulfate resisting within the limits of their territory.

NOTE 1       In addition to the specified requirements, an exchange of additional information between the cement manufacturer and user can 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 can be agreed between the parties concerned.

NOTE 2       The word “cement” in EN 197‑1 is used to refer only to common cements unless otherwise specified.
