BS EN 998-1:2016EN 998-1:2016 (E) 5 Introduction The characteristics of
24、 rendering and plastering mortars depend essentially on the type or types of binders used and their respective proportions. Special properties can be achieved by the type of aggregates, admixtures and/or additions used. Rendering/plastering mortars are defined: a) according to the concept as either:
25、 1) designed mortar; or 2) prescribed mortar. b) according to the mode of manufacture as either: 1) factory-made mortar; 2) semi-finished factory mortar; or 3) site-made mortar. c) according to the properties and/or use, as either: 1) general purpose rendering/plastering mortars; 2) lightweight rend
26、ering/plastering mortars; 3) coloured rendering mortar; 4) one-coat rendering mortar; 5) renovation rendering/plastering mortars; 6) thermal rendering/plastering insulating mortars. Rendering/plastering mortars do not attain their final characteristics until properly hardened after application. The
27、functions performed by a rendering/plastering mortar depend on the characteristics of the types of material used, on the thickness of the coats and the type of application. In addition, rendering/plastering mortars determine the surface of the construction. Regional differences in construction pract
28、ices and climate, and different constituents for rendering/plastering mortars do not allow for the establishment of standard mix proportions for prescribed mortar that would be applicable in all of Europe. Therefore, the specification of such mix proportions (recipes) and fields of application shoul
29、d be based on practice and experience available in the place of use. BS EN 998-1:2016EN 998-1:2016 (E) 6 1 Scope This European Standard is applicable to factory-made rendering/plastering mortars based on inorganic binders for external (rendering) and internal (plastering) use on walls, ceilings, col
30、umns and partitions. It contains definitions and final performance requirements. This European Standard provides for the assessment and verification of constancy of performance (AVCP) of the product to this European Standard. The marking requirement for products covered by this European Standard is
31、included. It does not cover mortars where calcium sulphate binder is the principal active binding agent. Calcium sulphate binder can be used as an additional binder together with air lime. If air lime is the principal active binding component, the rendering/plastering mortar is covered by this Europ
32、ean Standard. If the calcium sulphate binder is the principal active binding component, the mortar is covered by EN 13279. Special fire resistant- and acoustical mortars, mortars for structural repair and surface treatments of building elements such as materials for smoothing or trueing, paints, coa
33、tings, thin-layer organic renders/plasters and prefabricated units (e.g. plasterboards) are not dealt with in this European Standard. This European Standard covers rendering/plastering mortars defined in Clause 3 with the exception of site-made rendering/plastering mortars. However, this European St
34、andard or part of this European Standard may be used in conjunction with codes of application and national specifications covering site-made mortar. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicat
