    Revision of C1877 - 18 Standard Specification for Adhered Concrete Masonry Units

    (What is a Work Item?)

    Active Standard: C1877 - 19

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



    WK69572


    Keywords

    absorption; adhered; compressive strength; concrete facing units; concrete masonry units; linear drying shrinkage; portland cement; veneer;;

    Rationale

    Within ASTM C1877, both width and thickness are used to designated the dimension of the unit perpendicular to the wall face. This can cause confusion for users to the standard. In order to be consistent within this standard and with building code terminology, it is proposed in this ballot to use thickness consistently. It is also proposed to add a note in the Sampling and Testing section as the test standard (C140) refers to this dimension denoted as Ws during testing.
