polypropylene synthetic fiber
polypropylene synthetic fiber for Concrete Reinforcement
Product Description
Polypropylene synthetic fiber, also known as anti-crack fiber, PP fiber, construction fiber, or building fiber, is a high-strength bundled monofilament fiber made from polypropylene.
When added to mortar or concrete, it effectively controls microcracks caused by plastic shrinkage, drying shrinkage, temperature changes, and other factors. It prevents and suppresses the formation and expansion of cracks, significantly improving the concrete's crack resistance, impermeability, impact resistance, and seismic performance.
Product features
Inhibits and controls the formation of intrinsic cracking in concrete
Increases cohesion and reduces segregation
Reduces settlement and bleeding
Reduces plastic shrinkage and settlement cracking
Increases impact and shatter resistance
Reinforces against abrasion
Reduces freeze/thaw damage
Provides durability
Alternative system to traditional reinforcement when used for secondary (crack control) reinforcing in concrete
Application
(1) Reduces the risk of concrete cracking and enhances tensile, flexural, and bending strength.
(2) Minimizes damage during earthquakes and other extreme natural disasters.
(3) Decreases internal defects in concrete, improving impermeability.
(4) Protects reinforcement steel from corrosion, extending the durability of concrete structures.
(5) Increases wear resistance of concrete.
(6) Significantly improves fatigue resistance.
(7)Prevents tire damage when used in road construction.
