Designation:C1329/C1329M16aStandard Specification forMortar Cement1This standard is issued under the fixed designation C1329/C1329M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This specification covers three types of mortar cementfor use where mortar for masonry is required.1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard.Thevalues stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the two systems may result in non-conformance with the standard.Values in SI units shall beobtained by measurement in SI units or by appropriateconversion,using the Rules for Conversion and Roundinggiven in Standard IEEE/ASTM SI 10,of measurements madein other units.Values are stated in only SI units wheninch-pound units are not used in practice.1.3 The text of this standard refers to notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of the standard.1.4 The following safety hazards caveat pertains only toSection 16.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 Documents2.1 ASTM Standards:3C91 Specification for Masonry CementC109/C109M Test Method for Compressive Strength ofHydraulic Cement Mortars(Using 2-in.or 50-mm CubeSpecimens)C151 Test Method for Autoclave Expansion of HydraulicCementC183 Practice for Sampling and the Amount of Testing ofHydraulic CementC185 Test Method for Air Content of Hydraulic CementMortarC187 Test Method for Amount of Water Required for Nor-mal Consistency of Hydraulic Cement PasteC188 Test Method for Density of Hydraulic CementC219 Terminology Relating to Hydraulic CementC266 Test Method for Time of Setting of Hydraulic-CementPaste by Gillmore NeedlesC305 Practice for Mechanical Mixing of Hydraulic CementPastes and Mortars of Plastic ConsistencyC430 Test Method for Fineness of Hydraulic Cement by the45-m(No.325)SieveC511 Specification for Mixing Rooms,Moist Cabinets,Moist Rooms,and Water Storage Tanks Used in theTesting of Hydraulic Cements and ConcretesC778 Specification for Standard SandC1072 Test Methods for Measurement of Masonry FlexuralBond StrengthC1506 Test Method for Water Retention of HydraulicCement-Based Mortars and PlastersIEEE/ASTM SI 10 Standard for Use of the InternationalSystem of Units(SI):The Modern Metric System3.Terminology3.1 DefinitionsTerms used in this specification are definedin Terminology C219.3.2 Definitions of Terms Specific to This Standard:3.2.1 mortar cement,na hydraulic cement,primarily usedin masonry construction,consisting of a mixture of portland orblended hydraulic cement and plasticizing materials(such aslimestone or hydrated or hydraulic lime),together with othermaterials introduced to enhance one or more properties such assetting time,workability,water retention,and durability.3.2.1.1 DiscussionMortar cement is similar to masonrycement in use and function(see Specification C91).However,Specification C1329 includes a flexural bond strength require-ment.1This specification is under the jurisdiction of ASTM Committee C01 onCement and is the direct responsibility of Subcommittee C01.11 on MasonryCement.Current edition approved Dec.1,2016.Published December 2016.Originallyapproved in 1996.Last previous edition approved in 2016 as C1329/C1329M 16.DOI:10.1520/C1329_C1329M-16A.2Annual Book of ASTM Standards,Vol 04.01.See the section on SafetyPrecautions in the Manual of Cement Testing.3For 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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.Classification4.1 Mortar cements are classified as Type N,S,or M,according to the physical requirements prescribed in Table 1.5.Physical Properties5.1 Mortar cement shall conform to the applicable require-ments prescribed in Table 1 for its classification.6.Sampling6.1 At the option of the purchaser,the cement shall besampled and tested to verify compliance with this specification,sampling and testing shall be perfo
