PP Fiber Twisted Bunchy Form
Product Description
1. PP Fiber Twisted Bunchy Form is used to instead of steel fiber for reinforcement to cement concrete. Compared with steel fiber, PP Fiber Twisted Bunchy Form
has the advantage of easy dispersing and blending, no damage to the mixing equipments.
2. The rigid polymer fibre is used polypropylene as its raw material, produced the rough surface treatment by special parallel thread extruding & twisting process.
PP Fiber Twisted Bunchy Form It has high break strength, better dispersion and strong combining ability, will be widely used to instead of steel fibre reinforce the cement concrete and crack-resistant.
Application:
1. Ration design of the fibre concrete:
Generally the recommended amount to add to the concrete is more than 2.7kg per sqm (volume ratio is 0.3%), reinforcement adding amount is 5.5kg, Compared with adding 47kg of steel fibre, 5.4kg polymer fibre has the same volume ratio to the concrete.
2. Length: 54mm for common crack-resistant requirement.
3.
Mixing process:
Crushed stones, fibers and sands are put into the mixer in succession. After stirring for two minutes, 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 com-pletely mixed.
