Polypropylene Mixed Fibre PP Twist Fiber for Reinforced Concrete Engineering

Polypropylene Fiber Bunchy Form Product DescriptionPolypropylene Fiber (PP Fiber) is made from 100% virgin PP granular, after extruding from different mould and technology, we can get 4 different types of fiber, including Monofilament form, Fibrillated Mesh form, Twisted Bunchy and Wave form with different size. These fiber can improve the reinforcement of mortar or concrete performance effectively to make them strong and protect the projects.   Introduction:1. 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, etc2. 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.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 fibre, 5.4kg polymer fiber 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 m3 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 completely mixed6.  Shaping & Maintenance: There is no special requirement, may along the vibrating time for 30s, The maintenance of the fiber concrete should be done same as the normal concrete. Application: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 protection facilities.   Specification   Raw Material   Polypropylene   Fiber Type   Twisted Bunchy form   Length (mm)   40/48/50   Diameter (mm)   0.3+/-0.05   Strength (Mpa)   >560   Elastic Modulus (Mpa)   >5000   Break tesile ratio (%)   >15   Density   0.91   Product & Packing  Packing one:1).:  500g, or 1kg net per PE bag2).: 10kgs per plastic woven bag3).: 5000kgs/1X20`FCL without pallet4).: 13000kgs/1X40`HQ without pallet   Packing two:1).: 500g or 1kg net per water soluble paper bag.2).: 10kgs per carton3).: 450cartons/1X20`FCL without pallet4).: 1120cartons/1X40`HQ without pallet  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
