NBN EN 413-1:2004

This European Standard gives the definition and composition of masonry cements as commonly used in Europe for the production of mortar for bricklaying and blocklaying and for rendering and plastering. It includes physical, mechanical and chemical requirements and defines strength classes. prEN 413-1 also states the conformity criteria and the related rules. Necessary durability requirements are also given.
NOTE For normal applications the information given in prEN 413-1, in EN 998-1 and in EN 998-2 is generally sufficient. However, in special cases, an exchange of additional information between the masonry cement producer and user can be helpful. The details of such an exchange are not within the scope of prEN 413-1 but should be dealt with in accordance with national standards or other regulations or can be agreed between the parties concerned.
