ASTM WK44876

    Revision of C989 / C989M - 12a Standard Specification for Slag Cement for Use in Concrete and Mortars

    (What is a Work Item?)

    Active Standard: C989 / C989M - 14

    Developed by Subcommittee: C09.27 | Committee C09 | Contact Staff Manager


    1. Rationale

    Rationale: This Ballot Item proposes changes to the Scope Section 1.1 of ASTM C989/C989M-12a. Currently the Scope states that it covers three strength grades of slag cement This is misleading since grades are not technically strength grades, they are designations based on slag activity index values. Also the document is more encompassing than just grades and this scope statement should be more inclusive with other portions of C989 Standard Specification Proposed additions are underlined and proposed deletions are shown in strikethrough font. Only changes so indicated are being balloted. Other text is provided for information only.
