1、Designation:C869/C869M11(Reapproved 2016)Standard Specification forFoaming Agents Used in Making Preformed Foam forCellular Concrete1This standard is issued under the fixed designation C869/C869M;the number immediately following the designation indicates the yearof original adoption or,in the case o
2、f 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 specification covers foaming agents specificallyformulated for making preformed foam for use
3、in the produc-tion of cellular concrete.1.2 The function of this specification is to provide the meansfor evaluating the performance of a specific foaming agent.This is accomplished by using the foaming agent in making astandard cellular concrete test batch(see Test Method C796)from which test speci
4、mens are cast.Then,significant propertiesof the concrete are determined by tests and compared with therequirements of Section 3.1.3 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
5、,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.2.Referenced Documents2.1 ASTM Standards:2C796 Test Method for FoamingAgents for Use in ProducingCellular Concrete Using Preformed Foam3.Performance Requirements3.
