ASTM WK41410

    Revision of C926 - 12a Standard Specification for Application of Portland Cement-Based Plaster

    (What is a Work Item?)

    Active Standard: C926 - 15b

    Developed by Subcommittee: C11.03 | Committee C11 | Contact Staff Manager


    1. Rationale

    The term control-expansion joint is antiquated and no longer used within the standard since clarification has been provided on distinguishing these terms. Depending on their location the provisions of (2) and (3) may not comply with the requirements of the IBC. In instances where they do comply, experience has shown that these provisions have limited success in preventing cracks that can lead to water intrusion.
