    Free-flow Casting

    A low cement castable requiring no external vibration.

    • Compared with conventional cement castable refractories, it achieves high flowability with less mixing water, allowing the material to be cast easily into forms without external vibration or rodding.
    • Add the specified amount of water and mix in a mixer, then pour without vibration. When using free‑flow casting, appropriate formwork should be installed in advance.
    • Thanks to the action of ultra‑fine particles, the required strength can be achieved within 24 hours at ambient temperature.

    Main applications

    • High-temperature furnaces

  • THERVEK V
    Vibration Casting

    A low cement castable that achieves a dense structure exceeding that of conventional shaped refractories.

    • Designed for installation by vibration using a vibrator.
    • Although the mix has relatively low flow at the specified water content, vibration with a vibrator enables thorough filling of narrow spaces and complex shapes.

    Main applications

    • Various industrial kilns and furnaces
    • High-temperature furnaces
    • Incinerators
    • Boilers
  • THERVEK G
    Dry gunning

    Dry gunning material with excellent gunning performance and versatility.

    • Offers excellent adhesion with minimal rebound loss.
    • Using a gunning machine such as a Need Gun, the dry powder is conveyed by compressed air and mixed with water at the nozzle before being applied to the furnace wall.
    • Dry gunning requires no formwork or premixing, providing significantly higher installation efficiency than casting.

    Main applications

    • Various industrial kilns and furnaces
    • Incinerator combustion chambers
  • THERVEK C
    Casting Trowelling

    Easy to install with excellent versatility.

    • By adding the specified amount of water and mixing in a mixer, the material can be easily applied by casting or trowelling.

    Main applications

    • High-temperature furnaces
    • Various industrial kilns and furnaces
    • Incinerator combustion chambers
  • THERVEK PAT
    Patching

    A patching repair material with excellent adhesion.

    • Supplied in a workable, clay‑like consistency, softer than standard ramming plastics, and applied by hand patching (pressing into place).
    • Enables easy patch repairs of localized damaged areas in furnace linings.
    • After installation, initial adhesion is mechanical, but heating above 350°C sinters the material and significantly increases its strength.

    Main applications

    • Repair of various industrial kilns and furnaces
  • THERVEK AR
    Casting Dry gunning Trowelling

    The THERVEK AR Series is AGC Plibrico’s line of acid-resistant castables.
