Designation:C1435/C1435M14Standard Practice forMolding Roller-Compacted Concrete in Cylinder MoldsUsing a Vibrating Hammer1This standard is issued under the fixed designation C1435/C1435M;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 practice2covers molding cylindrical test specimensfrom concrete when the standard procedures of rodding andinternal vibration,as described in Practice C31/C31M andPractice C1176/C1176M,are not practicable.This practice isapplicable to freshly-mixed concrete,prepared in the labora-tory and the field.1.2 Freshly-mixed concrete is molded in cylindrical moldsusing an electric vibrating hammer equipped with a shaft andcircular plate.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.Within the text,theinch-pound units are shown in brackets.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 The text of this practice references notes and footnotes,which provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of this practice.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.2.Referenced Documents2.1 ASTM Standards:3C31/C31M Practice for Making and Curing Concrete TestSpecimens in the FieldC39/C39M Test Method for Compressive Strength of Cylin-drical Concrete SpecimensC172/C172M Practice for Sampling Freshly Mixed Con-creteC470/C470M Specification for Molds for Forming ConcreteTest Cylinders VerticallyC496/C496M Test Method for Splitting Tensile Strength ofCylindrical Concrete SpecimensC1170/C1170M Test Method for Determining Consistencyand Density of Roller-Compacted Concrete Using a Vi-brating TableC1176/C1176M Practice for Making Roller-CompactedConcrete in Cylinder Molds Using a Vibrating Table2.2 ACI Documents:ACI 207.5R Report on Roller-Compacted Concrete4ACI 211.3 Practice for Selecting Proportions for No-SlumpConcrete43.Summary of Practice3.1 This practice describes molding cylindrical concrete testspecimens using a vibrating hammer.Test specimens aremolded vertically in cylindrical molds by compacting the stiffto very dry concrete mixture in four lifts using a vibratinghammer.4.Significance and Use4.1 This practice,intended for use in testing roller-compacted concrete,may be applicable to testing other types ofcementitious material such as coarse-grained,soil-cement.Thispractice provides standardized requirements for molding stiffto very dry consistency concrete mixtures commonly used inroller compacted concrete construction.This practice is usedinstead of rodding or internal vibration,which cannot properlyconsolidate concrete of this consistency.NOTE1Further description of roller compacted concrete consistencyis given in ACI 207.5R and ACI 211.3.The consistency of concrete using1This practice is under the jurisdiction of Committee C09 on Concrete andConcrete Aggregates and are the direct responsibility of Subcommittee C09.45 onRoller-Compacted Concrete.Current edition approved Oct.1,2014.Published November 2014.Originallyapproved in 1999.Last previous edition approved in 2008 as C1435/C1435M 08.DOI:10.1520/C1435_C1435M-14.2Supporting data have been filed at ASTM International Headquarters and maybe obtained by requesting Research Report RR:C09-1045.ContactASTM CustomerService at serviceastm.org.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.4ACI Manual of Concrete Practice,Part 1,Materials and General Properties ofConcrete,American Concrete Institute,Farmington Hills,MI.*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 a vibrating table may be determined in accordance with Test MethodsC1170/C1170M.4.2 This practice is used to mold cylindrical test specimenscommonly used for testing compressive or tensile strength ofconcrete.Specimens tested for compressive strength and split-ting tensile strength shall be in accordance with Test MethodsC39/C39M and C496/C496M,respectively.Test specimensalso may be used to determine density of fresh concrete.NOTE2For some extremely dry mixtures;(those with a consistency
