ASTM WK34045

    Work Item: ASTM WK34045 - Revision of C1017 / C1017M - 07 Standard Specification for Chemical Admixtures for Use in Producing Flowing Concrete

    (What is a Work Item?)

    Active Standard: C1017 / C1017M - 13

    Developed by Subcommittee: C09.23 | Committee C09 | Contact Staff Manager



    1. Rationale

    Compliance with C09 policy on combined standards and inclusion of i) the C09.91 safety caveat on fresh hydraulic cementitious mixtures and ii) part of speech to definitions provided in terminology. (NOTE to Members: The oven temperature for determining oven-dried residue was not changed from 105 oC to the C09 standard oven temperature of 110 oC, because 105 oC is an established temperature designed to evaporate water but provide the least amount of possible thermal degradation of the active ingredients of chemical admixtures; and, currently, there is insufficient data to indicate that current oven-dried residue data would not be statistically different if the C09 standard oven temperature 110 oC is adopted.)
