    (What is a Work Item?)

    Active Standard: C1738 / C1738M - 18

    Developed by Subcommittee: C01.22 | Committee C01 | Contact Staff Manager



    WK63494


    Keywords

    cement paste; high-shear mixing; hydraulic cement; rheology;;

    Rationale

    The standard does not provide guidance on the optimal volume of material to be loaded into the mixer. Thus, a study was conducted to determine the influence of the volume of material and the mixer and a short report on the results obtained is provided below. The conclusions and recommendation of the report show that there is a minimum and a maximum optimal volume to ensure proper mixing of the materials. This ballot is to add guidance to the operator of C1738 on the optimal range of volume of materials.
