Glass fiber is a synthetic fiber which is categorized as micro fiber. This fiber is used for controlling the plastic shrinkage cracking.



For improving crack control in:


Concrete pavement

Bridge deck

Metal deck

Precast product



Reducing plastic shrinkage (effective crack control)

Increasing concrete toughness and fatigue resistance

Increasing life cycle

Increasing in precast production speed

Cost saving
