Designation:C41301(Reapproved 2012)Standard Test Method forAbsorption of Chemical-Resistant Mortars,Grouts,Monolithic Surfacings,and Polymer Concretes1This standard is issued under the fixed designation C413;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This test method covers the determination of the absorp-tion of chemical-resistant mortars,grouts,monolithicsurfacings,and polymer concretes.These materials may bebased on resin,silicate,silica,or sulfur binders.1.2 Mold Method A is used for systems containing aggre-gates less than 0.0625 in.(1.6 mm)in size.Mold Method B isused for systems containing aggregates from 0.0625 to 0.4 in.(1.6 to 10 mm)in size.Mold Method C is used for systemscontaining aggregates larger than 0.4 in.1.3 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.1.4 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C470/C470M Specification for Molds for Forming ConcreteTest Cylinders VerticallyC904 Terminology Relating to Chemical-Resistant Nonme-tallic Materials3.Terminology3.1 DefinitionsFor definitions of terms used in this testmethod,see 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 achemical-resistant material for a particular application.Noattempt has been made to incorporate in the test method all thevarious factors which may affect the performance of a materialwhen subjected to actual service.4.2 This is not a test for permeability and the test results arenot to be interpreted as a measurement of,or indication of,thepermeability properties of the materials tested.5.Apparatus5.1 Equipment,capable of weighing materials or specimensand for determining specific gravity to 60.03%accuracy.5.2 Equipment for Mixing,consisting of a flat-bottom con-tainer of suitable size,preferably corrosion-resistant,and atrowel having a 4 to 5 in.(100 to 125 mm)blade,and a spatulaor a rounded-end rod.5.3 Container,a glass flask of suitable size to hold thespecimens and the water and connected reflux condenser.5.4 Equipment for Heating,a hot plate or heating mantle.5.5 Specimen Molds:5.5.1 Mold Method AThese molds shall be right cylinders1 6132in.(25 6 0.8 mm)in diameter by 1 6132in.(25 60.8 mm)high.The molds may be constructed in any mannerthat will allow formation of a test specimen of the desired size.Typical molds may consist of a 1 in.thick flat plastic sheet inwhich 1 in.diameter,smooth-sided holes have been cut,and tothe bottom of which a14in.(6 mm)thick flat plastic sheet(without matching holes),is attached by means of screws orbolts.Alternatively,the molds may consist of sections of roundplastic tubing or pipe,1 in.in inside diameter and 1 in.long,having sufficient wall thickness to be rigid and retain dimen-sional stability during the molding operation,and a14in.thickflat plastic sheet on which one open end of each section can berested.With the latter style of mold,the tubing segment may besealed with a material such as caulking compound or stopcockgrease.For most types of specimens it is satisfactory to simplyseal one end of the tubing segment with strips of 2 in.widemasking tape.1This test method is under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.46 on Industrial Protective Coatings.Current edition approved Aug.1,2012.Published September 2012.Originallyapproved in 1958.Last previous edition approved in 2006 as C413 01(2006).DOI:10.1520/C0413-01R12.2For 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 NOTE1For use with sulfur materials,an additional piece of flat plasticsheet at least18in.(3 mm)thick containing a14in.(6 mm)hole and asection of plastic tubing 1 in.(25 mm)in diameter by 1 in.high arerequired.They are used to form a pouring gate and reservoir in thepreparation of sulfur material specimens.5.5.2 Mold Method BMolds for the 2 in.(50 mm
