Polypropylene Polymer Macro Synthetic Structural Fiber For Concrete

Product Description:

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

Application Instruction:

1. Ratio design of the fiber concrete:
Generally the recommended amount to add to the concrete is more than 2.7kg per sq/m (volume ratio is 0.3%, reinforcement adding amount is 5.5kg. Compared with adding 47kg of steel fiber, 5.4kg polymer fiber has the same volume ratio to the concrete.
2. Length: 50mm for common crack-resistant requirement.
3. Matching Ratio:Usually, there 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 polypropylene fiber-mesh with the volume ratio of 1:1 (0.9kg fiber-mesh per sq/m of
cement concrete).
4. Mixer Adoption: Double-axle horizontal compelling mixer is priority.
5. Mixing process: Crushed stones, fibers and sand are put into the mixer in succession. After stirring for two minutes, the fiber will by fully spread. Cement and water are then added and mixed normally. fiber also can be added last into common concrete, but the stirring time should be
properly prolonged to ensure the fiber is completely mixed.
6. Shaping & Maintenance: There is no special requirement, The finishing of the fiber concrete should be done the same as for normal concrete.

Technical parameter:

Applications:

1. The surface of 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.

4. Improve the crack-resistence in large scale of cement concrete for industrial workshop, warehouse, parking lot, airport, underground engineering, Hydraulic work ect.
