ASTM WK46740

    Revision of C937 - 10 Standard Specification for Grout Fluidifier for Preplaced-Aggregate Concrete

    (What is a Work Item?)

    Active Standard: C937 - 10

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



    WK46740

    1. Rationale

    Currently C937 only allows mixing of trial batches in 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 C939 to harmonize this change.
