    (What is a Work Item?)

    Active Standard: C140 / C140M - 20a

    Developed by Subcommittee: C15.03 | Committee C15 | Contact Staff Manager



    WK75809


    Keywords

    absorption; compressive strength; concrete masonry units; density; equivalent thickness; face shell; moisture content; roof paver; web area; webs; web thickness;;

    Rationale

    Currently, the standard requires to measure both the length and the width of slabs, but does not provide any guidance as to which lateral dimension is which. For concrete pavers (Annex A4), the length is the larger of the lateral dimensions. It is proposed here to include the same language in Annex A8 for slabs.
