This European Standard shall be given the status of a national standard, e
21、ither by publication of an identical text or by endorsement, at the latest by March 2005, and conflicting national standards shall be withdrawn at the latest by June 2006. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association,
22、 and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This document for binders, composite binders and factory made mixtures for floor screeds based on calcium sulfate consists of two part
23、s: Part 1: Definitions and requirements Part 2: Test methods This document specifies binders, composite binders and factory made mixtures where the principal active constitu- ent is calcium sulfate. The requirements in EN 13454-1 on binders and composite binders are based on the results of tests acc
24、ording to EN 13454-2. The requirements on factory made mixtures for floor screeds based on calcium sulfate are in accordance with EN 13813. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following coun- tries are bound to implement this European Standa

26、1 Scope This document applies to calcium sulfate binders and composite binders made of calcium sulfate used for the manufacture of floor screeds for interior use in buildings. It also includes requirements for factory made mixtures made of calcium sulfate used for the manufacture of floor screeds wh
27、ich are given in EN 13813. This document does not cover the application of floor screeds. Floor screeds made with products covered by this document may contribute to thermal and sound insulation and fire protection of the floor. 2 Normative references The following referenced documents are indispens

32、xample hemihydrate and anhydrite 3.2 additives materials added to calcium sulfate binder or mixture by the manufacturer to influence the chemical and/or the physical properties NOTE Additives are, for example, fillers, pozzolans, pigments and artificial resins 3.3 admixtures materials added to the b
33、inder or mixture in small quantities and which, by chemical or physical action or both, change the properties of the calcium sulfate constituent, e.g. its workability, hardening or setting NOTE Admixtures are, for example accelerators, retarders and plasticizers EN 13454-1:2004 (E) 6 3.4 aggregates
34、materials consisting of uncrushed and/or crushed mineral material with particle sizes and shapes suitable for the production of floor screeds 3.5 screed layer or layers of screed material laid in situ, directly onto a base, bonded or unbonded, or onto an intermediate layer or insulating layer, to ob
35、tain one or more of the following purposes: to obtain a defined level, to carry the final flooring, to provide a wearing surface 3.6 binder material used for the purpose of holding solid particles together in a coherent mass 3.7 consistency fluidity of fresh screed material which characterises its e
36、ase of use 3.8 flow diameter dimension for consistency of stiff factory made mixtures 3.9 spread dimension for consistency of flowing and highly plastic mixtures 4 Types of binders and factory made mixtures 4.1 Calcium sulfate binders (CAB) Calcium sulfate binders (CAB) consist of calcium sulfate co
37、nstituents binding by hydration and may contain admix- tures and additives (see 5.2.a). 4.2 Calcium sulfate composite binders (CAC) Calcium sulfate composite binders (CAC) consist of calcium sulfate binders (CAB) and contain additional additives (see 5.2.b). 4.3 Factory made mixtures (CA) Factory ma
38、de mixtures (CA) consist of binders or composite binders and aggregates and may contain admixtures and additives with or without water. The means of determining the suitability of the aggregates for use in factory made mixtures shall be recorded in the manufacturers documentation of the factory prod
39、uction control. With respect to the manufacturing methods, factory made mixtures shall be suitable for application in one of the three consistencies: stiff, highly plastic or flowing (see 6.9). If calcium sulfate binders or calcium sulfate composite binders, as specified in this document, are used f
40、or the manufacture of factory made mixtures, the tests specified in EN 13454-2 for determination of the pH value and for determination of shrinkage and swelling need not to be carried out. Factory made mixtures can be produced and delivered as: EN 13454-1:2004 (E) 7 a) prebatched (dry) in a factory
41、and mixed on the construction site in factory specified proportions and conditions, b) premixed (dry) in a factory and mixed on the construction site by adding water, c) ready mixed (wet) which is supplied to the construction site in a pre-mixed and gauged condition. 5 Requirements for binders (CAB;
