What is BS EN 197-1 - Conformity criteria for common cements about?
BS EN 197-1 is the European standard that defines and gives the specifications of 27 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 that the constituents have to meet. It also includes mechanical, physical, and chemical requirements.
Furthermore, BS EN 197-1 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.
