Pyrok - 304

Insulating cement mortar to fireproof metal structures in accordance with the hydrocarbon curve.

Scope of application:
  • Fireproofing metal structures, concrete and mixed slabs, as well as other structural elements in buildings and factories in general.

  • Strengthening ceramic top slabs or similar in a poor state of repair.

  • Heat insulation for floor slabs and walls.

  • Fireproof rendering inside tunnels.

  • Acoustic absorption in buildings.

  • Avoids the collapse of all kinds of structural elements in the event of a fire.

Properties:
  • Cement mortar (M – 40), completely asbestos-free.

  • Tested resistance to fire of up to three hours.

  • Does not emit toxic gases or smoke during application or in the event of a fire.

  • Excellent holding and adherence properties on both metal structures and concrete slabs and other structural elements.

  • Insensitive to mildew, insects and rodents.

  • Chemically inert and does not decompose or age.

Format:
  • 20-kg bags.

  • 60-bag pallet.

Pouring:

a) Surface:
  • Remove any traces of dust using mechanical means.
  • The surface must be clean, steady and dust-, oil- and grease-free.


    • b) Application:
  • Mechanical system: Hexagonal wire netting (40 mm) properly secured to the structure. Wet spraying machines with a worm gear pump are recommended.
  • Manual System: Use standard construction tools. The proportion of water per bag is 10 to 12 litres.

    • Cleaning tools:

    PYROK can be removed using water before it has set. Once it has set, it can only be removed using mechanical machines.


    Storage:

    It can be stored for 12 months in its original sealed packaging in a dry place.


    Tests:
    1. Metal beams and pillars up to EF-240 minutes.

    2. Reinforced concrete slab RF-120 minutes.
