Synthetic Fibres

Two types of synthetic fibres are available. The details of each can be found below.

 

Non-Structural Synthetic Fibres

Micro fine fibres are normally added at 0.6kg/m3 to provide early age crack control. Scancem's Nycon fibres are nylon. Unlike polypropylene, nylon absorbs a small amount of water giving excellent bonding. This accounts for why the fibres give excellent early age (ie plastic stage) crack control. Applications include:

Structural Synthetic Fibres

Structural synthetic fibres are large diameter (approx 1mm) polypropylene fibres that are highly deformed to increase mechanical bond. Normally dosed at 5-15kg/m3 they provide high ductility, particularly at high deflection. Applications include:
