Product Description

Macro-Synthetic Fiber
Polypropylene Crude Fiber
(PPTF)

Chemical Nature

Polypropylene crude fiber(PPTF) is a substitute product developed for steel fiber while considering some characteristics of synthetic fiber. Compared with steel fiber, it has attributes with corrosion resistance, easy dispersion and construction, and no damage to mixing equipment. PPTF is made of synthetic resin as the primary raw material, processed through unique technology and surface treatment. It has the advantages of high breaking strength, good dispersion in concrete, and strong gripping force. It can replace steel fiber for cement concrete and overcome the weakness of concrete, such as low tensile strength, low ultimate elongation, and brittleness. In addition, it has properties like tensile resistance, shear resistance, crack resistance, fatigue resistance, and high toughness. The applying fields of PPTF are covered in engineering, such as construction, roads, bridges, and hydraulic engineering.

Features of application

Application of PPTF concrete

1. Polypropylene Crude Fiber concrete has high flexural and tensile strength and can use for culvert support, mountain slope protection, and other support projects;
2. Polypropylene Crude Fiber concrete has high crack resistance and can be used in basement anti-seepage, reservoirs, low-pressure water pipelines, and other projects;
3. Polypropylene Crude Fiber concrete has high impact and abrasion resistance and can be used in high-speed water flow parts such as spillways, stilling tanks, and gate floors of water conservancy and hydropower projects;
4. Polypropylene Crude Fiber is made of synthetic materials with the features of steel fiber, so it has more advantages when used in concrete projects in corrosive environments such as seawater;
5. Polypropylene Crude Fiber has high tensile strength, fracture toughness, and fatigue resistance; it can be applied in parts bearing dynamic loads, such as roads, railway bridges, and other projects.

Economic comparison

Polypropylene Crude Fiber is developed for the use of steel fiber; its cross-sectional shape and specific surface area are similar to steel fiber, so it can be assumed that they have the same specific surface area when comparing the economy of the two materials. Furthermore, although the gravity of steel is 7.8kg /cm³and Polypropylene Crude Fiber is 0.95kg/cm³, under the same volume content, the steel fiber's weight is eight times that of the Polypropylene Crude Fiber. Therefore, it is obvious to see that replacing steel fiber with Polypropylene Crude Fiber can significantly reduce costs.
 

Usage

 Instructions

★Dosage: The volume dosage of crack-resistant imitation steel fiber should be 0.3%-0.9%; the dosage per cubic meter of concrete is 3kg-9kg.  

★Length selection: Generally, it is 30mm-50mm when anti-cracking is reinforced; it is 20mm-30mm when mixed into shotcrete.

★Proportion design: It is unnecessary to change the concrete grade and proportion parameters for general applications. Instead, refer to "Steel Fiber Concrete Structure and Construction Code" CECS38: 92., special applications must be selected and designed through experiments. Considering that concrete will shrink due to shrinkage, drying shrinkage, temperature changes, and other factors that cause tiny cracks, 1kg of monofilament microfiber can be added to the concrete for better effect.

★Mixer selection:It is recommended to choose a double-shaft horizontal forced mixer.

★The material feeding and mixing process: Put in crushed stone and  PPTF, and sand in order, stir to make PPTF fully dispersed, then set in cement and water and mixed evenly according to the conventional process. It can also be constructed according to the sequence of standard process input, but the mixing and stirring time should be extended appropriately to make the PPTF disperse evenly.

★Molding maintenance process: There is no special requirement, and the time for vibrating can extend as appropriate. When plastering the surface, the concrete surface should be slightly passivated before proceeding to avoid it being carried out. The maintenance should still be carried out according to the requirements of ordinary concrete.
