TB PP Twisted Bundle Fiber is similar to steel fiber,which is made of pp or pe, and mainly used for concrete reinforcement.
TB PP Twisted Bundle Fiber is made of 100% polypropylene or polythene by special technique. TB-Twisted-Fiber has the advantages of high-breaking tenacity, high-gripping force and excellent dispersivity in concrete. Moreover, compared with the steel fiber, it has the special features of anti-corrosion, anti-dispersion ,anti-operation, no damage to the mixing equipment, etc
Physicochemical Properties
Regular Spec: TB-Twisted-54S
Material Form | Polythene or Polypropylene | Identical Diameter (mm) | 0.5±0.1 |
Color | Gray | Elongation at break (%) | ≥15 |
Length (mm) | 54±2 | Tensile Strength (MPa) | ≥380 |
Density (dtex) | 0.91~0.94 | Modulus of Elasticity(MPa) | ≥2500 |
Note: The range of length 10-56mm, and according to your demand
Function
Decrease the danger from crack of concrete; increase intensity of anti-stretch, anti-bending, anti-breaking of the concrete
Decrease the breakage when earthquake or other terrible natural disasters happen
Decrease the inner fatal defect of concrete; increase the anti-infiltration performance of concrete
Protect the steel bar from corroding; increase the durability of concrete structure
Increase the abrasive resistance of concrete
No abrasion to the mixing equipment
Prevent the damage to tires
Application
For culverts support, natural terrain revetment and other support engineering, owe to its high anti-bending and tensile strength
For the impounding reservoirs, low pressure-water pipes and the anti-infiltration of the basements, because of its high performance of anti-crack
For the position of high-speech running water, e.g., the spillways and sluice boards of the Hydraulic and Hydro-Power Engineering, because of its high performance of anti-impact and anti-abrasion
Better for the concrete engineering in the condition of being corroded by the seawater, because it is made of synthetic resin with the specialty of the steel fiber
For bearing the live load, such as bridges of the highway, railways and other engineering, because its high performance of fracture toughness, anti-stretch, anti-fatigue etc
Compare with the Steel Fiber in Economy
TB PP Twisted Bundle Fiber is made according to the function of steel fiber. Their shape of cross section and specific surface area are similar to steel fiber, so when compare the economy of the two kind of material, we could suppose that they have the same specific surface area and the proportion of the reinforced anti-crack tendon is 0.95kg/cm3, the proportion of steel is 7.8g/cm3, under the condition of same adding volume, the weight of steel fiber is 8.0 times of the anti-crack tendon’s, so it is clear that use anti-crack tendon can reduce the cost quite a lot than use steel fiber.
