ASTM WK46743

    Revision of C938 - 10 Standard Practice for Proportioning Grout Mixtures for Preplaced-Aggregate Concrete

    (What is a Work Item?)

    Active Standard: C938 - 10

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


    1. Rationale

    The mixer shown in Fig. 1 is the only mixer allowed for proportioning of mixtures. It is felt that allowing a mixer specified by project specifications would produce proportioning results more similar to those used for work while still allowing the C938 mixer to be used if not such specifications exist. There is no commercial source for the mixer and this issue has been identified by CCRL as cause for findings in laboratory inspections.
