    Active Standard: C311 / C311M - 18

    Developed by Subcommittee: C09.24 | Committee C09 | Contact Staff Manager



    WK75554


    Keywords

    fly ash; natural pozzolan;;

    Rationale

    This ballot proposes changes to ASTM C311 to clarify requirements as to cements used in testing. Low-alkali portland cement is no longer defined in ASTM C150 and these changes make clear what the requirements are for cements used in ASR-related testing.
