Usage

For most types of non-structural concrete and cementitious mortars which need to reduce the incidence of shrinkage cracking:
  • Ground bearing slabs
  • Screeds and overlays
  • Renders and plasters
  • Precast concrete elements
  • Sprayed applications
  • Extruded concrete
  • Interior and exterior applications
 

Advantages

  • Safe and easy to use

Application

Application Information

DISPENSING

Add the fibres with the dry aggregates taking care to evenly distribute the fibres throughout the mix.
The fibres can be added when all the mix components have been added, although the mixing time will need to be increased to ensure a uniform fibres distribution (as a guide add 1 extra minute for every 1m3). Do not add the fibres directly into the mixing water.
Consumption

Recommended Dosage

~600 g or 900 g per m3 concrete.

To reduce spalling at high temperatures 1000–2000 g per m3 concrete
