ASTM WK30116

    Revision of C1435 / C1435M - 08 Standard Practice for Molding Roller-Compacted Concrete in Cylinder Molds Using a Vibrating Hammer

    (What is a Work Item?)

    Active Standard: C1435 / C1435M - 08

    Developed by Subcommittee: C09.45 | Committee C09 | Contact Staff Manager



    WK30116

    1. Rationale

    Increasing the upper range of the hammer mass will expand the number of hammers that can meet the standard. Increasing the mass of the tamping plate and shaft assembly will allow for a more robust design of the tamping foot which should reduce the failure rate of the manufactured tamping foot assemblies. Increasing the overall mass of the apparatus will lessen the influence of operator supplied force on the specimen. Increasing the diameter of the tamping plate will improve edge compaction of the RCC and limit the amount of paste loss when preparing the specimen.
