Description
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).
USES
SikaFibre® M 12 mm can be used for:
▪Airport apron and car park slabs
▪Concrete and mortar subjected to impact loads
▪Thin applications of shotcrete or gunite
▪Precast concrete to decrease demoulding time
▪Concrete needing high cohesion such as extruded concrete or when laying concrete on agradient
CHARACTERISTICS / ADVANTAGES
Due 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)
