    Automatic Grinding Machine

    Automatic Grinding Machine

    The SCTC-1040 Automatic Grinding Machine provides fast grinding of
    cylinder specimen ends to obtain plane and parallel surfaces according to EN and ASTM standards.
    Three units of Ø38 to 100 mm or two units of Ø150-160 mm concrete cylinders ends can be ground
    simultaneously with the suitable cradle and water restraint panel. The length of the any specimen
    must be longer than 70 mm.
    According to ASTM and EN standards, the planeness accuracy of grinded surface is 0.05 mm. and the
    deviation of perpendicularity of the side with reference to the end faces is 0,5°
    .
    The equipment has selectable advance grinding time functionality by user from 50 to 400 seconds.
    Optimum grinding time per end of all type specimens is 90 to 120 seconds.
    The cradle which specimens are fixed on has automatic bidirectional radial displacement ability. The
    safe and ergonomic design prevents the user to exposure to water and dust and provides easy access
    to the water inlet and outlet. Specimen cradles and water restraint panels can easily be installed
    without the need for any assembly.

    Original Schmidt Test Hammer

    Original Schmidt Test Hammer

    SCTR-0563 Type L Hammer is a portable and relatively inexpensive instrument for measuring the
    surface hardness of rock. The hammer can be used efficiently in both laboratory and the field setting.
    The mechanism of operation is simple: a hammer released by a spring, indirectly impacts against the
    rock surface through a plunger and the rebound is read on scale of hammer then compressive
    strength is read directly from the curve ranging from 10 to 70 MPa (1,450 to 10,152 psi).
    The type L hammer is used on NX or larger core specimens or block specimens having an edge length
    of at least 6 cm.
    SCTC-3040 Calibration Anvil, manufactured from a special steel alloy, is used for the calibration of

    Rock Schmidt-Rock Test Hammer

    Rock Schmidt-Rock Test Hammer

    SCTR-0564 Rock Schmidt Test Hammer (Proceq) is the world’s most advanced rebound hammer fully
    adapted specifically to the extremely varied rock testing applications (Testing on cores and blocks).
    The RockSchmidt incorporates statistical methods based on ASTM and ISRM recommendations and
    provides the user with the freedom to define his own statistical process for determining a rebound
    number

    FEATURES
    Impact Angle Independence: The rebound value is independent of the impact direction.
    Optimized for Field Work: Tighter sealing against dirt and dust intrusion for longer life. Significantly
    lighter and more ergonomic than the classic Schmidt hammer. A large number of readings can be
    saved and downloaded later to a PC.
    Preset Statistics: Statistics methods recommended by ISRM and ASTM are implemented into the
    hammer for automatic calculation of the rebound number. The option is also there to define a user
    specific statistics method.
    Unconfined Compressive Strength: ISRM recommends a correlation between UCS and the rebound
    value based on the formula UCS = aebR (where R is the rebound value). A correlation in this format
    may be defined in the PC software and downloaded onto the RockSchmidt.
    E-Modulus: ISRM recommends a correlation between elastic modulus and the rebound value based
    on the formula Et = cedR (where R is the rebound value). A correlation in this format may be defined
    in the PC software and downloaded onto the RockSchmidt.
    Weathering Grade: Impacting on the same location twice can be used to correlate to weathering
    grade. The ISRM recommended method has been included in the device.
