    Keywords

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

    Rationale

    The span length for modulus of rupture is based on the length of the slab. There is ambiguity, however, on what span length is to be used for slabs that are exactly 20 inches in length. This ballot proposes to clarify that the largest span length should be used for slabs 20 inches and greater.
