EN 13579:2002 (E)41 ScopeThis European Standard specifies a test method to evaluate the effect of hydrophobic impregnation on the dryingrate coefficient of impregnated specimens. The method primarily relates to the protection of concrete structures.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN 1766, Products and systems for the protection and repair of concrete structures - Test methods - Referenceconcretes for testing.EN 13580, Products and systems for the protection and repair of concrete structures - Test methods - Waterabsorption and resistance to alkali for hydrophobic impregnations.3 SymbolsSymbolExplanationUnitCnConsumption of impregnant for each face of test cube during treatmentg/m2CmMean consumption of impregnant during treatmentg/m2d0Weight of a test cube prior to placing in environmental cabinetgd1Weight of a test cube after initial conditioning in environmental cabinetgd2Weight of a test cube at end of drying testgDRCDrying Rate Coefficient%DtDrying rate of a treated test cubeg/m2 × hDtmMean drying rate of three treated test cubesg/m2 × hDuDrying rate of an untreated test cubeg/m2 × hDumMean drying rate of three untreated test cubesg/m2 × hM’tEstimated moisture content of each test cube after conditioning%MmMean saturated surface dry moisture content of 3 oven dry test cubes%MssdSaturated, surface dry moisture content of a test cube, calculated%W¢odEstimated weight of a test cube in oven dry conditiongWodWeight of a test cube in oven dry conditiongWssdWeight of a test cube in saturated surface dry conditiongWtActual weight of test cube after conditioninggWt1Weight of test cube immediately prior to treatmentgWt2Weight of test cube immediately after treatmentgSIST EN 13579:2002



EN 13579:2002 (E)54 PrincipleThe principle of the test method described in this European Standard is to compare the rate of drying of treated anduntreated test cubes from the same batch of concrete. The ratio of the rates is defined as the drying ratecoefficient.5 Apparatus5.1Nine moulds for concrete cubes (100 mm
x 100 mm x 100 mm).5.2Soft brush.5.3Absorbent paper towel5.4Balance with an accuracy of 0,01 g.5.5Support for test cubes on bench in labora
