FIBERMESH® 150 Monofilament Fibre for Concrete

100% VIRIGIN POLYPROPYLENE MICRO FIBRE FOR CONCRETE

Micro-synthetic monofilament fibre for concrete. Tens of millions of fibres per cubic metre.

Tested to show over 90% reduction in plastic shrinkage cracking compared to control.

Patented e3 technology – fibre is graded by length, thickness and mix ratio – to significantly reduce the tendency of concrete containing fibres to shrink or to crack during initial drying shrinkage.

Virtually invisible in finished concrete.

Suitable for use in driveways, footpaths, slab on grade (not for residential housing), architectural and decorative concrete, exposed aggregate concrete, etc.

12mm FM 150 increases resistance to explosive spalling in high strength concrete exposed to fire (BB2 rating).

Fibermesh 150 fibres were previously BRANZ appraised as an alternative system to wire mesh for crack control for slab on ground floors and pavements. Changes to NZ Standards have discontinued the use of micro-synthetic fibres as a replacement for wire mesh in slab on ground floors for habitable structures. In these applications, please refer to Forta Ferro macro fibres. Fibermesh 150 fibres may be used in external concrete, driveways, footpaths, etc  and in conjunction with wire mesh to help prevent cracking.

Minimum dosage:
1 bag per m3 of concrete

 

Expressly formulated to address early age cracking problems, Fibermesh micro-synthetic fibres prevent 80 -100% of all cracks in the plastic state – precisely when most cracks occur. During the plastic settlement phase, the fibres create a three-dimensional support network that resists the downward pull of gravity, thus keeping aggregates in suspension and promoting uniform bleeding.

This network increases the tensile strain capacity of concrete during the plastic shrinkage phase as well.

Fibermesh 150 consists of different lengths and thicknesses of fibres in the same bag to better match the distribution of aggregate sizes and void spaces in the concrete. Fibermesh 150 fibres offer superb plastic shrinkage crack reduction and are virtually invisible in the cured concrete.

   
 
Fibermesh 150 is compliant with European Standard 14889-2
