Designation:D586095(Reapproved 2022)Standard Test Method forEvaluation of the Effect of Water Repellent Treatments onFreeze-Thaw Resistance of Hydraulic Cement MortarSpecimens1This standard is issued under the fixed designation D5860;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers a procedure for determining thecomparative effect of water repellent treatments on the freeze-thaw cycling of hydraulic cement mortar specimens.1.2 This test method is designed to compare the effective-ness of water repellent treatments under conditions of freezingand thawing only.This test method is intended as a laboratoryscreening method for treatment selection and may not accu-rately reflect the performance of treated and untreated speci-mens in the field.This test method is not intended to duplicatefield conditions.1.3 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2C109/C109M Test Method for Compressive Strength ofHydraulic Cement Mortars(Using 2-in.or 50 mm CubeSpecimens)D1193 Specification for Reagent WaterD1475 Test Method for Density of Liquid Coatings,Inks,and Related ProductsE145 Specification for Gravity-Convection and Forced-Ventilation Ovens3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 water repellent treatment,na transparent penetratingsealer or surface-applied treatment formulated for the purposeof protecting porous substrates by reducing the penetration ofliquid water.4.Summary of Test Method4.1 Mortar specimens are treated with or immersed in awater repellent material,removed,and allowed to cure.Afterair drying,the treated specimens are weighed then subjected tovarious cycles of freezing and thawing.Periodic weighing andobservations are made to determine weight loss and deleteriouseffects such as spalling and cracking.5.Apparatus5.1 Balance,having a capacity of not less than 400 g and asensitivity of 0.1 g.5.2 Corrosion-resistant Metal Pan,that is,aluminum,forimmersion of substrates.5.3 Weight per Litre(Gallon)Cup.5.4 Freezing Chamber,capable of maintaining 19.2 61.4 C(2.5 6 2.5 F).5.5 Forced Draft Oven,capable of maintaining 110 6 5 C(230 6 9 F).5.6 Stiff-nylon-bristled Brush.6.Test Materials6.1 50-mm(2-in.)mortar cubes greater than 28-days old,and prepared in accordance with procedures outlined in TestMethod C109/C109M,have been found suitable for this testmethod.These cubes should be brushed with a wire brush orlightly sand blasted to remove form oil or release agent before1This test method is under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.47 on Concrete,Stone and Masonry Treatments.Current edition approved Jan.1,2022.Published January 2022.Originallyapproved in 1995.Last previous edition approved in 2013 as D5860 95(2013).DOI:10.1520/D5860-95R22.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1using.Five test specimens will be used for each treatment,andfive untreated controls shall also be included for each test.Allcubes should come from the same lot of material.NOTE1Preferably,rather than make each cube individually,a largecake can be made.25-mm(1-in.)should be cut off each face of the caketo remove any residual form release oil.Cubes are cut from the cake tomeasure 50 by 50 by 50 mm(2 by 2 by 2 in.)to be used as mortarspecimens.6.2 Water repellent treatments.7.Procedure7.1 Dry the required n
