ASTM WK46087

    Revision of C109 / C109M - 13 Standard Test Method for Compressive Strength of Hydraulic Cement Mortars (Using 2-in. or [50-mm] Cube Specimens)

    (What is a Work Item?)

    Active Standard: C109 / C109M - 13

    Developed by Subcommittee: C01.27 | Committee C01 | Contact Staff Manager



    WK46087

    1. Rationale

    Current language in Section 5.6.1 of C109, tells the user to check the tamper for design and dimensional requirements at least every 2.5 years. This is unacceptable timeframe as the rectangular rubber tampers become worn, rounded and can peel in much less than 2.5 years. New language will be proposed.
