ASTM WK47011

    Revision of C1761 / C1761M - 13b Standard Specification for Lightweight Aggregate for Internal Curing of Concrete

    (What is a Work Item?)

    Active Standard: C1761 / C1761M - 13b

    Developed by Subcommittee: C09.21 | Committee C09 | Contact Staff Manager



    WK47011

    1. Rationale

    Currently the standard calculates the absorption (A72) as a percent of oven dry mass in section 10.5.1 and reports it in 10.6.1.7. The desorption (WLWA) is currently calculated as a fraction of oven dry mass in section 11.5.1 and reported in 11.6.1.6. Because absorption is in % and desorption is a fraction, the users of the standard are finding it hard to interpret the results.
