EN 13581:2002 (E)41 ScopeThis European Standard is one of a series dealing with products and systems for the protection and repair ofconcrete structures. It specifies a method for determining the loss of mass after freeze-thaw salt stress in sodiumchloride solution. It can be used to test the resistance of hydrophobic impregnated concrete as well as theuntreated concrete. There are two types of concrete deterioration when a freeze-thaw attack occurs: surfacescaling and internal damage.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 - Referenceconcrete for testing.3 SymbolsSymbolExplanationUnitCDifference between the reached number of cycles of untreated and treated testcubes-CConsumption of impregnant during treatmentg/m2CabsQuantity of fluid absorbed of one test cube during immersion in 3 % NaCl-solution%Cabs, mQuantity of fluid absorbed of four test cubes during immersion in 3 %NaCl-solution; Mean value of treated an untreated test cubes%CmMean consumption of impregnant during treatmentg/m2CnConsumption of impregnant for each face of the cube during treatmentg/m2CuReached number of cycles of untreated test cubes-CtReached number of cycles of treated test cubes-nIndicating the number of cycles carried out-DWnChange of mass after the n cycle%WnMass of a test cube after n cyclesgW0Mass of a test cube before immersion for 24 h in 3 % NaCl solutiongWt1Mass of test cube immediately prior to treatmentgWt2Mass of test cube immediately after treatmentgWeMass of a test cube after immersion for 24 h in 3 % NaCl solutiongSIST EN 13581:2002



EN 13581:2002 (E)54 PrincipleThe principle of the test method described in this standard is to compare the loss of mass and visible defects oftreated and untreated test cubes from the same batch of concrete. The difference between the reached cycles oftreated and untreated test cubes characterizes the effectiveness of a hydrophobic impregnant.5 Apparatus5.1Eight moulds for concrete cubes (100 mm x 100 mm x 100 mm).5.2Laboratory or chamber maintained at constant temperature (21 ± 2) °C and relative humidity of (60 ± 10) %.5.3Four brass or stainless steel watertight containers with a width of (120 ± 10) mm, a length of (260 ± 10) mmand a height of (150 ± 10) mm. The sheet metal shall be approximately 1 mm thick. The containers are closed withlids which shall be designed so that they cannot be lifted off when the chamber is flooded. The lid of one containershall have an opening for placing a thermocouple to measure the temperature in the centre of one test cube.5.4Thermocouples, or an equivalent temperature measuring device with which the temperature shall bemeasured to an accuracy of 0,5 °C. A continuous recording device shall be used measuring and recording thetemperature at least every 10 min over a period of 24 h.5.5An automatically-controlled freezing chamber with a flooding device. The performance of the freezingchamber shall be designed so that it is possible to maintain the temperature cycle referred to Figure 1 for each ofthe test cubes placed in it.5.6Brush, with short (about 20 mm), soft bristles for brushing off scaled material.5.7Spray bottle, containing tap water for washing off scaled material.5.8Drying cabinet, for a temperature of at least 110 °C.5.9Balance, wi
