500MPa Fibrillated Polypropylene Twisted Fiber for Precast Concrete

500MPa Fibrillated Polypropylene Twisted Fiber for Precast Concrete

Luke 500Mpa polypropylene twisted fiber is engineered specifically for precast concrete manufacturing.It's been a huge help in solving precast concrete'ss biggest problems.example: demolding cracks, edge chipping during lifting, rust stains on exposed surfaces, and the labor-intensive work of tying wire mesh.As low dosage pp twisted fiber it requires only 0.6-1.2kg/m³，far less than steel fiber or wire mesh and delivers excellent crack control and impact resistance.This precast concrete fiber tackles the most common headches head on :demolding cracks that ruin your finish, edge chipping during lifting and transportation, rust stains on exposed surfaces, and the labor-intensive work of tying wire mesh by hand. With its unique twisted, hinged geometry, the fiber locks firmly into the concrete matrix, disperses uniformly in seconds,— helping precast factories boost their reject rate, speed up production cycles, and lower total cost, all while delivering a perfect, rust-free finish every time.

The concrete fiber polypropylene twisted Fiber technical parameters:

Product features and advantages:

◆High toughness:

Twisted bunchy polypropylene fiber elongation at break ≥ 15%, effectively absorbs impact energy, and has excellent seismic performance.

◆Good dispersion:

The polypropylene twisted fiber concrete fiber is easy to disperse in concrete and can be evenly distributed.

‌◆Strong gripping force: 

THE polypropylene fiber can be firmly attached to the concrete, enhance its crack resistance.

‌◆High cracking strength:

Concrete  pp fiber has a high cracking strength, can withstand greater stress.

◆Acid and alkali corrosion resistance:

It has good acid and alkali resistance.

‌◆High elastic modulus:

PP twisted fiber concrete fiber has a high elastic modulus, can resist deformation.

Polypropylene fiber concrete fiber applying instruction:

1、PP twisted fiber polypropylene fiber for concrete dosage:no less than 3kg/cubic meter of concrete for high crack level(volume ratio:0.3%);for general level, it can use compound fiber of 0.8kg twisted bundle PP fiber and 0.4kg PP fiber mesh.

2、Stirring requirement: crusted stones, fibers and sands are put into the mixer in succession. After stirring for 2 minutes, fiber will fully spread and then add cement and water and stir normally. The addition of materials also can be put into as usual ,but the stirring time should  be properly prolonged to more than 4 minutes to make fiber completely mixed.
