1. General
1.1 Description:
Macrosol fibres are extruded from a natural virgin Polypropylene homo polymer, formed into a waved profile for concrete and mortar reinforcement and other composite materials
1.2 Qualities
Standard quality
o Polypropylene compound
1.3 Coatings (If Applicable)
1.4 Concept and terms
L : the nominal length in mm,
de : the nominal diameter in mm,
Factor λ : the length-to-diameter ratio (L/d). This parameter is important to the properties of the concrete or mortar for which Macrosol fibres are used.
2. Explanation of used symbols
o Form of delivery: L = Loose
o Shape of fibre: R = Round Corrugated Shaped anchorage
o Performance class: is approximately the (L/d) = 50
o Length of the fibre: indicative length of the fibre in mm = 40 mm
o Fibre Type: SS = Structural Synthetic fibre
2.1 No of fibres per kg
Approximately 44 000 per kg (Calculated)
3. Properties based on ASTM Requirements
