17、 This document supersedes EN 459-1:2010. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. For relationship with Regulation (EU) No. 305/2011, see informative Annex ZA, which is an integral part of this document. EN 459,

18、Building lime, consists of the following parts: Part 1: Definitions, specifications and conformity criteria; Part 2: Test methods; Part 3: Conformity evaluation.

21、ntroduction The revision of this European Standard for building lime was initiated by Decision 4 taken by CEN/TC 51 “Cement and building limes” in 2013. Different sources of raw materials and different climatic conditions have led to different developments in building construction and civil engineer

22、ing practices and materials and therefore to different kinds of building lime in different regions of Europe. The inclusion of a wider range of building lime which exists in Europe has made it necessary to establish a number of classes. The previous national standards for building lime generally als

23、o formed the basis for different areas of application (see Annex C (informative). The classification chosen therefore also takes into consideration these circumstances as far as possible. For a better understanding, the standard makes a clear distinction between air lime (Clause 4) and lime with hyd

24、raulic properties (Clause 5). Depending on the composition and characteristics of the products, each clause is then divided into sub-paragraphs (calcium lime and dolomitic lime for air lime; natural hydraulic lime, formulated lime and hydraulic lime for lime with hydraulic properties) containing the

25、 appropriate definitions, specifications and conformity criteria. BS EN 459-1:2015EN 459-1:2015 (E) 5 1 Scope This European Standard applies to building lime used for: preparation of binder for mortar (for example for masonry, rendering and plastering); production of other construction products (for

26、 example calcium silicate bricks, autoclaved aerated concrete, concrete, etc.); civil engineering applications (for example soil treatment, asphalt mixtures, etc.). It gives definitions for the different types of building lime and their classification. It also gives requirements for their chemical a

27、nd physical properties which depend on the type of building lime and specifies the conformity criteria. Terms of delivery or other contractual conditions, normally included in documents exchanged between the supplier and the purchaser of building lime, are outside the scope of this European Standard

28、. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any ame

Reaction with atmospheric carbon dioxide is

34、part of the hardening process. Lime with hydraulic properties is divided into three sub-families, natural hydraulic lime (NHL), formulated lime (FL) and hydraulic lime (HL). 3.5 allowable probability of acceptance CR for a given sampling plan, allowed probability of acceptance of building lime with

38、, relating to the intended tests Note 1 to entry: It can be obtained by combining one or more immediately consecutive increments (see EN 4592). 3.11 autocontrol testing continual testing by the manufacturer of building lime spot samples taken at the point(s) of release from the factory/depot 3.12 co

40、ir lime (see 3.3) when appropriately batched and mixed with water, forms a paste that improves the workability (values of flow and penetration) and water retention of mortars. The carbonation of hydrates in contact with atmospheric carbon dioxide forms calcium carbonate which develops strength and c

41、ontributes to the durability of mortars containing building lime (hence the name of air lime). Sub-families and forms of air lime are given in 4.2 and 4.3 respectively. 4.2 Sub-families of air lime 4.2.1 Calcium lime (CL) Calcium lime is an air lime consisting mainly of calcium oxide and/or calcium

42、hydroxide without any hydraulic or pozzolanic addition. 4.2.2 Dolomitic lime (DL) Dolomitic lime is an air lime consisting mainly of calcium magnesium oxide and/or calcium magnesium hydroxide without any hydraulic or pozzolanic addition. 4.3 Forms of air lime 4.3.1 Quicklime (Q) Quicklime is an air

43、lime mainly in the oxide form which reacts exothermically on contact with water. Quicklime is available in a range of sizes from lump to powder. 4.3.2 Hydrated lime (S, S PL or S ML) Hydrated lime is an air lime mainly in the hydroxide form produced by the controlled slaking of quicklime. Hydrated l

44、ime is available as: powder (S); putty (S PL); or slurry or milk of lime (S ML). Dolomitic lime is also produced as semi-hydrated dolomitic lime (S1), mainly consisting of calcium hydroxide and magnesium oxide. 4.4 Calcium lime 4.4.1 Classification of calcium lime Calcium lime shall be classified ac

45、cording to the notation given in Table 1 and its total (CaO + MgO) content in accordance with Table 2. BS EN 459-1:2015EN 459-1:2015 (E) 8 Table 1 Types of calcium lime aDesignation Notation Calcium lime 90 CL 90 Calcium lime 80 CL 80 Calcium lime 70 CL 70 aIn addition, calcium lime is classified ac

46、cording to the form of the product, quicklime (Q), hydrated lime (S), lime putty (S PL) or milk of lime (S ML). Conformity with this classification is assessed by means of statistical quality control as described in Annex A of this European Standard. 4.4.2 Chemical requirements for calcium lime The

47、properties of the type of calcium lime shown in Table 2 determined in accordance with EN 459-2 shall conform to the requirements in that table. All types of calcium lime listed in Table 2 may contain additives in small quantities to improve the manufacture or properties of calcium lime. When the tot

48、al content exceeds 0,1 %, the actual types and amounts shall be declared.

49、 55 The values for CaO + MgO, MgO, CO2and SO3are applicable to all forms of calcium lime. For quicklime these values correspond to the finished product; for all other forms of lime (hydrated lime, lime putty and milk of lime) the values are based on the product after subtraction of its free water and bound water content. The values for available lime (calcium oxide for quicklime, calcium hydroxide for hydrated lime) refer to the product when tested in accordance with EN 4592. aMgO content up to 7 % is permitted if
