PP twisted fiber used in projects

BD CHEMICAL PP twisted fiber introduction:

1. This fiber is used instead of steel fiber for reinforcement to cement concrete. Compared with steel fiber, it has the advantage of easy dispersing and blending, no damage to the mixing equipment, etc

2. The rigid polymer fiber is used polypropylene as its raw material, producing the rough surface treatment by a special parallel thread extruding & twisting process. It has high break strength, better dispersion, and strong combining ability and will be widely used instead of steel fiber to reinforce cement concrete, and is crack-resistant.

Function ：

1.?Decrease the crack of concrete; increase the intensity of anti-stretch, anti-bending, and anti-breaking of concrete.

2.?Decrease breakage when earthquakes or other terrible natural disasters happen.

3.?Decrease inner fatal defect of concrete; increase the anti-infiltration performance of concrete.

4.?Protect steel bars from corroding; increase the durability of the concrete structure.

5.?Increase abrasive resistance of concrete.

6.?No abrasion to mixing equipment.

7.?Prevent damage to tires.

Apply Instruction:

1. Ration design of the fiber concrete:

Generally, the recommended amount to add to the concrete is more than 2.7kg per m3(volume ratio is 0.3%), reinforcement adding amount is 5.5kg, Compared with adding 47kg of steel fiber, 5.4kg of polymer fiber has the same volume ratio to the concrete.

2. Length: 54mm for the common crack-resistant requirement.

3. Matching Ratio:

Usually, it is no need to change the matching ratio of the concrete. Considering the requirement of fissure-resistant, the polymer fiber is recommended to combine with the PP fiber mesh form with the volume ratio of 1:1 (0.9kg fiber-mesh to per m3 of cement concrete).

4. Mixer Adoption: Double-axle horizontal compelling mixer is a priority.

5. Mixing process:

Crushed stones, fibers, and sands are put into the mixer in succession. After stirring for two minutes, the fiber will fully spread, and then add cement and water and stir normally. The addition of materials also can be put into as common concrete, but the stirring time should be properly prolonged to make fiber completely mixed

6. Shaping & Maintenance:

There is no special requirement, may along a vibrating time of 30 seconds, The maintenance of the fiber concrete should be done the same as the normal concrete.

Application:

1. The surface of the road, bridge, runway, and floor of the factory.

2. Wall and roof of the tunnel and mine.

3.?Dam, river, bridge pier, dock, and military protection facilities.

For concrete that meets the biggest challenges, withstands the harshest conditions, and stands the test of time.
