Product Description Company Profile Product Descriptionpp macro fiber introduction: Briture Synthetic Macrofiber is made of Polypropylene.These fibers are wrapped in bundles of water-soluble film and packed in cartons. When used, just put the whole boxes of the fibers into concrete. The cartons and film are dissolved in water and the fibers are evenly dispersed in the concrete mixture.Available Length: 48mm, 54mm, 64mm...FeaturesAll grades of concrete to provide good anti - fatigue, anti - shrinkage, anti - seismic and good toughness.Simple operation, not easy to group, safety, reasonable price, cost savings..It can be used in highly corrosive, humid environment.The surface has been embossed, which greatly improved the cohesive force between fibers and concrete, and also boosts shrinkage resistance and crack resistance.The strength of synthetic macro fiber is not as strong as that of steel fiber, but the experiment shows that under the same conditions, each cubic meter concrete needs 3kg-6kg of synthetic macro fiber, while steel fiber needs 25kg-40kg. The results show that the concrete with macro synthetic fiber has better toughness and anti-microcrack effect. Proposed DosageThe dosage rate is dependent on the actual application however the minimum dosage range is 3kg/ m3-6kg / m3Typical ApplicationShotcrete, concrete engineering, such as foundations, roads, Bridges, DAMS, especially in the deformation and toughness of the higher requirements of the project, such as mining and water conservancy and hydropower projects.

These fiber can improve the reinforcement of mortar or concrete performance effectively to make them strong and protect the projects. Product Description1. This fibre is used to instead of steel fiber for reinforcement to cement concrete.2. The rigid polymer fibre 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 fibre toreinforce the cement concrete and crack-resistant. APPLYING INSTRUCTION: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 is5.5kg, 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. 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 recommend to combine with the PP fiber mesh form with the volume ratio of 1:1(0.9kg fiber-mesh to per sqm of cement concrete). .4. Mixer Adoption:Double-axle horizontal compelling mixer is priority.5. 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.6. Shaping & Maintenance:There is no special requirement, may along the vibrating time for 30s, The maintenance of the fibre concrete should be done same as the normalconcrete.
