Designation:C1176/C1176M13Standard Practice forMaking Roller-Compacted Concrete in Cylinder Molds Usinga Vibrating Table1This standard is issued under the fixed designation C1176/C1176M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This practice covers procedures for making cylindricaltest specimens from concrete when the standard procedures ofrodding and internal vibration,as described in Practice C31/C31M,are not practicable.This practice is applicable to freshlymixed concrete,prepared in the laboratory and the field,havinga nominal maximum size aggregate of 50 mm 2 in.or less.Ifthe nominal maximum size aggregate is larger than 50 mm 2in.,the practice is applicable only when performed on thefraction passing the 50-mm 2-in.sieve with the largeraggregate being removed in accordance with Practice C172.This practice,intended for use in testing roller-compactedconcrete,may be applicable to testing other types of concretesuch as cement-treated aggregate and mixtures similar tosoil-cement.1.2 Two methods are provided for making concrete cylin-ders using a vibrating table:1.2.1 Method A is a procedure for making test specimens insteel reusable molds attached to a vibrating table.1.2.2 Method B is a procedure for making test specimens insingle-use plastic molds that have been inserted into a metalsleeve attached to a vibrating table.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.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 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:2C31/C31M Practice for Making and Curing Concrete TestSpecimens in the FieldC39/C39M Test Method for Compressive Strength of Cylin-drical Concrete SpecimensC172 Practice for Sampling Freshly Mixed ConcreteC192/C192M Practice for Making and Curing Concrete TestSpecimens in the LaboratoryC470/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 TableE11 Specification for Woven Wire Test Sieve Cloth and TestSieves3.Summary of Practice3.1 This practice describes methods for making cylindricalconcrete test specimens using a vibrating table.Test specimensare made in cylindrical molds that are attached to the vibratingtable under a 9-kg 20-lb surcharge to facilitate consolidation.4.Significance and Use4.1 This practice is intended to be used for stiff to extremelydry concrete mixtures commonly used in roller-compactedconcrete construction.This practice is used instead of roddingor internal vibration,which cannot properly consolidate con-crete of this consistency(Note 1).NOTE1Further description of this concrete consistency is given inACI 207.5 Roller-Compacted Mass Concrete3and 211.3 Guide for Se-lecting Proportions for No-Slump Concrete3.The consistency of roller-compacted concrete may be determined in accordance with Test MethodC1170/C1170M.1This practice is under the jurisdiction of ASTM Committee C09 on Concreteand ConcreteAggregates and is the direct responsibility of Subcommittee C09.45 onRoller-Compacted Concrete.Current edition approved Dec.15,2013.Published February 2014.Originallyapproved in 1991.Last previous edition approved in 2008 as C1176 08.DOI:10.1520/C1176_C1176M-13.2For 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.3ACI Manual of Concrete Practice,Part 1,Materials and General Properties ofConcrete,2005,American Concrete Institute(ACI),P.O.Box 9094,FarmingtonHills,MI 48333.*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 5.Apparatus5.1 Molds:5.1.1 Type A MoldA cylindrical mold conforming to therequirements of Specification C470/C470M for 150-mm 6-in.diameter by 300-mm 12-in.high reusable molds.Molds shallbe made of steel or other hard metal not readily attacked by thecement paste.Aluminum molds shall not be used.Molds shallbe equipped with permanently affixed metal slotted brackets
