polypropylene crude fiber
polypropylene crude fiber for Concrete Reinforcement
Product Description
Polypropylene crude fiber uses synthetic fibers as raw materials. Through special processes and surface treatments, it offers high breaking strength, excellent dispersion in concrete, and strong bonding force. Replacing steel fibers in cement concrete, it addresses the material's low tensile strength, limited ultimate elongation, and brittleness.
The fiber provides tensile resistance, shear resistance, crack prevention, fatigue resistance, and high toughness. It has been widely used in construction, roads and bridges, hydraulic engineering, and other fields.
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). Suit for the waterproof layer, floor, inner & outer wall of industrial and civil construction.
(2). Increase cracking resistance on the surface of industrial workshop, warehouse and parking lot.
(3). Increase cracking & seepage resistance of the ground in natatorium, swimming pool, pond and ditch.
(4). Suit for any mortar projects and common concrete projects.
(5). Highway, bridge and other roads.
(6). Prevent shrinkage in ready-mix concrete and precast concrete.
(7). Fire-resistant concrete structure.
(8). Precast concrete segments for final lining of tunnels.
