ASTM WK35944

    Revision of C469 / C469M - 10 Standard Test Method for Static Modulus of Elasticity and Poisson's Ratio of Concrete in Compression

    (What is a Work Item?)

    Active Standard: C469 / C469M - 14

    Developed by Subcommittee: C09.61 | Committee C09 | Contact Staff Manager



    WK35944

    1. Rationale

    A general revision is proposed to make the procedure clearer and to incorporate changes made to Test Method C39/C39M. Provision 6.1 is not enforceable. The concern is that a change in temperature may affect the deformation measurement system. The provision in 6.4 is vague so it is proposed that the specimen be loaded three times. Section 6.4 is subdivided to make the steps clearer.
