Designation:C143913Standard Test Methods forEvaluating Latex and Powder Polymer Modifiers for use inHydraulic Cement Concrete and Mortar1This standard is issued under the fixed designation C1439;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.Scope*1.1 These test methods provide a means of determining theeffect of adding polymer modifiers to reference concrete ormortar.1.2 Most sections of ASTM test methods and practices forhydraulic cement mortar and concrete apply to the preparationand testing of specimens made with polymer-modifiers.However,there are some exceptions,most notably curing,thatneed special procedures in order to develop the propertiesinherent with polymer-modification.These test methods coverthese exceptions.1.3 For testing polymer-modified mortar and concretespecimens,the procedures in this standard supersede those inthe referenced ASTM test methods and practices.These testmethods are not applicable to dry,packaged mortar andconcrete.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 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.(WarningFreshhydraulic cementitious mixtures are caustic and may causechemical burns to skin and tissue upon prolonged exposure.2)2.Referenced

Specification for Latex and Powder Polymer Modi-fiers in Hydraulic Cement Concrete and Mortar1These test methods are under the jurisdiction of ASTM Committee C09 onConcrete and ConcreteAggregatesand are the direct responsibility of SubcommitteeC09.44 on Polymer-Modified Concrete and MortarsCurrent edition approved Oct.1,2013.Published October 2013.Originallyapproved in 1999.Last previous edition approved in 2008 as C1439 08a.DOI:10.1520/C1439-13.2Section on Safety Precautions,Manual of Aggregate and Concrete Testing,Annual Book of ASTM Standards,Vol.04.02.3For referenced ASTM standards,visit

Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.Significance and Use3.1 These test methods are used to develop data for com-parison with the requirements of Specification C1438.Stan-dardized procedures are used to compare the properties ofspecimens made from test mixtures of polymer-modified con-crete or mortar with the properties of specimens made fromreference mixtures.These test methods are not intended tosimulate job conditions.4.Materials4.1 polymer modifierthe polymer modifier of the requiredtype as furnished by the supplier.4.2 antifoam agentantifoam agent of the type recom-mended by the manufacturer,if one is not incorporated in thepolymer modifier.
