ASTM WK41965

    Revision of C94 / C94M - 13 Standard Specification for Ready-Mixed Concrete

    (What is a Work Item?)

    Active Standard: C94 / C94M - 15a

    Developed by Subcommittee: C09.40 | Committee C09 | Contact Staff Manager


    1. Rationale

    When a small batch of concrete is mixed in a concrete mixer, a significant portion of the mortar may adhere to the inside of the mixing drum. This will result in the concrete that is discharged from the drum having different characteristics than the designed concrete mixture. Tests of this concrete will not be representative of the designed concrete mixture.
