ASTM WK46744

    Revision of C939 - 10 Standard Test Method for Flow of Grout for Preplaced-Aggregate Concrete (Flow Cone Method)

    (What is a Work Item?)

    Active Standard: C939 - 10

    Developed by Subcommittee: C09.41 | Committee C09 | Contact Staff Manager


    1. Rationale

    Currently C939 only allows testing of mixtures using the mixer shown in Fig. 1 of C938. It is felt that allowance should be made to mix the trial batches according to project specifications and equipment with the C938 mixer still to be used if no specifications exist. Concurrent to the ballot change wording is being proposed for C938 and C937 to harmonize this change.
