Also known as SikaFibre® Monofilament 12 mm, SikaFibre® M 12 mm is based on specially treated polypropylene. They are added to concrete mixes to reduce shrinkage cracking in the plastic stage. SikaFibre® M 12 mm is monafilament for wet batch mixes (> 35 mm slump).
UsesSikaFibre® M 12 mm can be used for:
Airport apron and car park slabs
Concrete and mortar subjected to impact loads
Concrete needing high cohesion such as extruded concrete or when laying concrete on a gradient
Thin applications of shotcrete or gunite
Precast concrete to decrease demoulding time
Characteristics & AdvantagesDue to their fineness and special surface treatment, SikaFibre® M 12 mm can be easily dispersed in the concrete or mortar and create a dense matrix that leads to:
Improved cohesiveness of the fresh concrete
Reduction of shrinkage cracks
Increased resistance to impact loads
Reduced concrete permeability
Resistance to slab curling
Improved fire damage properties
Note: SikaFibre® M 12 mm is 18 microns in diameter which is smaller than most other fibres in the market. This fineness gives a greater number of fibres per kg (~180 million per m² of concrete) and a greater effective surface area (225 m² per kg).
