Product Name: Seepage Resistant Shotcrete Tunnel Modern Construction Materials and Techniques
Company introduction:
Our company Chongqing Joywell Trade Co., Ltd. is a foreign trade company. With its 14 years’ experience, now our main products are building materials and medical equipment. Of all the building materials (construction materials ), plastic fiber(synthetic fiber ) and steel fiber are the two types of fibers used for construction. Plastic fiber is also called, synthetic fiber, concrete fiber, engineering fiber or construction fiber. It includes PP ( polypropylene ) fiber of all types, such as monofilament, mesh, twisted bundle and curved, PAN ( polyacrylonitrile ) fiber, PVA ( polyvinyl alcohol ) fiber, PET ( polyester ) fiber and glass fiber. These fibers are used to fill in the cement concrete, asphalt concrete or mortar to improve reinforcement of concrete. Nowadays, these fibers are necessary and widely used in construction and engineering projects.
Curved PP macro fiber introduction:
Curved PP fiber is a new type of construction materials used for concrete reinforcement. It is used to take the place of steel fibre to reinforce the cement concrete in construction. it has the advantage of easy dispersing, crack resistance, and easy for construction. And there is no need for any special maintenance.
Specifications:
Raw Material | Polypropylene | Identical Diameter | 0.8-1.2mm |
Color | white | Type | curved |
Length(mm) | 19, 25, 30, 40, 50mm | Tensile Strength | >400Mpa |
E-modulus | >3500Mpa | Crack Elongation | 15±5% |
Density | 0.91g/cm³ | Melting Point | >160°C |
Use instruction:
1. Recommand Adding Amount: 5.4kg curved PP fiber per concrete CBM.
2. Length for choose : 50mm for reinforceent or crack resistance; 19mm for shotcrete.
3. Mixing process: Put into the crushed stones at first, then put the curved PP fiber and
sand in succession into the blender. Stir them for 2 minutes to make fibers mixed completely. Then
add the cement and water to them and stir by normal standard.
Function of Curved PP Fiber:
1. Decrease the danger from crack of the concrete; increase the intensity of anti-stretch, anti-bending.
2. Decrease the breakage when earthquake or other terrible natural disasters happen
3. Decrease the inner fatal defect of the concrete.
4. Protect the steel bar from corroding; increase the durability of the concrete structure
5. Increase the abrasion resistance of the concrete
6. No abrasion to the mixing equipment
Two types of curved PP macro fiber:
