SYNTHETIC FIBRES FOR CONCRETE AND MORTAR

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

•  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 & 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).
