    (What is a Work Item?)

    Active Standard: C595 / C595M - 13

    Developed by Subcommittee: C01.10 | Committee C01 | Contact Staff Manager



    1. Rationale

    There is an expressed concern that loss-on-ignition (LOI) provisions for ternary cements with limestone could permit high LOI fly ash in a blended cement, which could impact entrainment of air in concrete. This ballot adds an LOI limit to alleviate the concern.
