Designation:C137000(Reapproved 2012)Standard Test Method forDetermining Chemical Resistance of Aggregates for Use inChemical-Resistant Sulfur Polymer Cement Concrete andOther Chemical-Resistant Polymer Concretes1This standard is issued under the fixed designation C1370;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 the determination of the effectsof selected environments on aggregates for use in manufactur-ing sulfur polymer cement concrete(SC)and other chemical-resistant polymer concretes.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C904 Terminology Relating to Chemical-Resistant Nonme-tallic Materials2.2 National Institute of Standards and Technology:Avail-able from National Institute of Standards and Technology(NIST),100 Bureau Dr.,Stop 3460,Gaithersburg,MD 20899-3460.Handbook 44 Specifications Tolerances and other TechnicalRequirements for Commercial Weighing and MeasuringDevices3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this test method,referto Terminology C904.4.Significance and Use4.1 The results obtained by this test method should serve asa guide in,but not as the sole basis for,selection of aggregatesfor use in sulfur polymer cement concrete and other chemical-resistant polymer concretes for a particular application.Noattempt has been made to incorporate in the test method all thevarious factors that may affect the performance of a materialwhen subjected to actual service.4.2 This test method assists in determining whether aggre-gates are susceptible to attack by solutions in the environmentof intended use.4.3 This is not a test for permeability and results are not tobe interpreted as a measurement of,or indication of,perme-ability of the material tested.5.Apparatus5.1 Weighing Equipment,shall be capable of weighingmaterials or specimens to 60.3%accuracy.The weighingequipment shall meet the National Institute of Standards andTechnology requirements for sensitivity and tolerances.NOTE1In general,small quantities should not be weighed on largecapacity scales.In many applications,the smallest quantity weighed on ascale should be greater than about 10%of the maximum capacity of thescale;however,this will vary with the performance characteristics of thescale and the required accuracy of the determination.Acceptable scalesused for weighing concrete materials preferably should weigh accuratelyto about 0.1%of total capacity and the foregoing precaution is applicable.However,certain analytical and precision balances are exceptions to thisrule and should weigh accurately to 0.001%.Particular care must beexercised in measuring small quantities of material by determining thedifference between two much larger weights.5.2 Drying oven of sufficient size to accommodate theaggregate sample and capable of holding the sample at atemperature of 230 6 10F(110 6 6C).5.3 Small Tools,including,but not limited to,items such as600-mL beakers,hot plate capable of holding sample andsolution at constant 140 6 4F(60 6 2C),desiccator,filterflask,funnel,and No.1 qualitative filter papers.6.Materials Preparation6.1 The temperature in the vicinity of the mixing and testingoperations shall be 73 6 4F(23 6 2C).1This test method is under the jurisdiction of ASTM Committee C03 onChemical-Resistant Nonmetallic Materials and is the direct responsibility ofSubcommittee C03.01 on Mortars and Carbon Brick.Current edition approved Aug.1,2012.Published September 2012.Originallyapproved in 1997.Last previous edition approved in 2005 as C1370 00(2005).DOI:10.1520/C1370-00R12.2For 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 States1 6.2 The temperature of the aggregate test specimens willvary and sometimes exceed 212F(100C).7.Procedure7.1 Dry aggregate to constant weight,cooling in a desicca-tor before weighing.Weigh three 200-g specimens of aggre-gate.Record the initial weight(W1)of aggregate.Place eachaggregate specimen in a separate beaker and weigh the 200-gspecimen,beaker,and
