    Revision of C78 / C78M - 18 Standard Test Method for Flexural Strength of Concrete (Using Simple Beam with Third-Point Loading)

    (What is a Work Item?)

    Active Standard: C78 / C78M - 18

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



    WK71549


    Keywords

    beams; concrete; flexural strength testing; modulus of rupture ;;

    Rationale

    It was brought to the attention of C9.61 that some labs inadvertently use the cement testing head on top of their flexural strength apparatus. This ballot was created to clarify the testing apparatus when a spherical seated bearing block is utilized in place of the uppermost bearing plate shown in Fig. 1 and to harmonize it with C39/C39M
