This European Standard specifies 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 mechanical, physical and chemical requirements and defines strength classes. EN 413-1 also states the conformity criteria and the related rules; necessary durability requirements are also given. The main changes from EN 413-1:2004 are as follows: - introduction of a class MC 22,5 air-entrained cement; - removal of references to EN 459-2 for compressive strength testing; - the upper limit for SO3 content is increased. The responsible German committee is NA 005-06-23 AA "Putz- und Mauerbinder" ("Masonry cement") at the Building and Civil Engineering Standards Committee (NABau).
