Sikacrete®-213 F

WET SPRAYED MORTAR FOR FIRE PROTECTION

Cement based pre-bagged, dry mix fire protection mortar for wet sprayed application especially for concrete structures in tunnel construction. Suitable for use in hot and tropical climatic conditions.

  • Pre-bagged dry mortar mix for wet spray applications
  • Minimal layer thickness to meet specifications
  • Easy to apply
  • Does not contribute to the formation of smoke or toxic fumes in fire
  • Light weight, low density
  • The sprayed mortar surface can be finished by trowel or wood float
  • Minimal rebound

Usage

Sikacrete®-213 F is used for concrete and reinforced concrete structures exposed to fire hazards.
It contains phyllosilicate aggregates, which are highly effective in resisting the heat of hydrocarbon fires. The thickness of the fire protection layer to be applied depends on the specified fire resistance. The outstanding properties of Sikacrete®-213 F allow greatly reduced thickness of the fire protection layer required. Can be used on Sika® FRP structural strengthening systems to upgrade fire resistance.

Consumption

Consumption

~6 kg/m2 for a layer thickness of 10 mm


This figure is theoretical and does not include for any additional material required due to surface porosity, surface profile, variations in level and
wastage etc..

Above consumption is calculated based on dry material density after 28 days curing, applied by spray method.
Application steps

MIXING

Sikacrete®-213 F shall be mixed using a forced action mixer.

Pour the minimum recommended amount of clean water in the mixing container. While stirring slowly, add the powder to the water and mix thoroughly at least for 3 minutes adding additional water if necessary to the maximum specified amount and adjust to the required consistency.

 

APPLICATION

Sikacrete®-213 F is applied by wet spray dense-flow process.
Thoroughly pre-dampen the prepared concrete substrate. To achieve the optimum physical characteristics, the spray nozzle must be handled by a trained and experienced operator.
Application equipment: Wet spray screw pump systems.
Reinforcement: The use of light wire mesh reinforcement (Example: Bekaert Armanet FP, Fischer or equivalent) is always recommended in order to prevent any debonding of the mortar layer.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanicallly.
