Shell limes are hydrated calcium limes produced by calcination of shells followed by slaking.Carbide limes are hydrated calcium limes which are a by-product of the manufacture of acetylene from calcium carbide.

The values are applicable to all kinds of lime. For quicklime these values correspond to thefinished product; for all other kinds of lime (hydrated lime, lime putty and hydraulic limes) the valuesare based on the product after subtraction of its free water and bound water content.aValues given in percent by mass.bSO3 content of more than 3 % and up to 7 % is permissible, if soundness is demonstrated at28 days of water curing using a test given in EN 196-2.cMgO content up to 7 % is acceptable if a soundness test given in 5.3 of EN 459-2:2001 ispassed.4.4Standard strength requirements and other physical properties4.4.1Standard strength requirements for hydraulic limeThe standard strengths of the types of hydraulic lime and natural hydraulic lime are the compressive strengthsdetermined in accordance with EN 459-2:2001 after 28 days and shall have the values given in Table 3.Table 3 – Compressive strength of hydraulic lime and natural hydraulic limeType of building limeCompressive strengthMPa7 days28 daysHL 2 and NHL 2-³ 2 to £ 7HL 3,5 and NHL 3,5-³ 3,5 to £ 10HL 5 and NHL 5³ 2
³ 5 to £ 15aaHL 5 and NHL 5 with a bulk density lower than 0,90 kg/dm³ is allowed tohave a strength up to 20 MPa.7

It is known, that mortars containing lime binders also acquire compressive strength which increase slowly withcarbonation.4.4.2Other physical properties for quicklimes and hydrated LimesPhysical properties in Table 4 and 5 of building limes shall comply with the relevant values given therein when testedin accordance with EN 459-2:2001.

Additional propertiesOther properties, also determined in accordance with EN 459-2:2001, may be subject either to requirements inexecution standards dealing with the use of limes or to queries from the users. These properties are given in theinformative annex C.4.5Durability requirementsIn many applications, particularly in severe environmental conditions, the choice of building limes has an influence onthe durability of mortar and other construction products, e. g. frost resistance and chemical resistance.The choice of building lime, from this European Standard, particularly as regards type and strength class for differentapplications and exposure classes shall follow the appropriate standards and/or regulations for mortar and otherconstruction products valid in the place of use.8

General requirementsConformity of building lime with this standard shall be continuously evaluated on the basis of testing of spot samples.The properties to be tested, test methods and the minimum testing frequencies for each type and classification ofbuilding lime as detailed in Table 1 for the autocontrol testing by the manufacturer are specified in Table 6.The declaration of conformity by the manufacturer, shall be based on the evaluation of conformity of building limewith this European Standard according to the scheme specified in EN 459-3:2001.NOTE Requirements for the EC declaration of conformity which the manufacturer must have available under the CEmarking procedure are established in annex ZA and should not be confused with other types of declaration of conformity.5.2
Conformity requirementsSampling shall take place at the points of release of the building lime.Conformity of building lime with the requirements concerning strength, physical and chemical properties in thisstandard is assumed if the requirements in Tables 2 through 5 are met. The requirements in Tables 2, 3, 4 and 5shall be taken as absolute values.The evaluation procedure depends on the frequency of testing during the control period of 12 months. If the numberof samples is at least 1 per week, the evaluation may be statistical (characteristic values) (see annex B).Statistical evaluation is normally by attributes (see Table 6 and B.4). If the data are normally distributed, theevaluation may be made by variables (see Table 6 and B.3).NOTE This standard does not deal with acceptance inspection at delivery.10
