Product Name: Earthquake Resistant Building Materials for Concrete Reinforcing
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.
PVA fiber introduction:
PVA fiber is short for polyvinyl alcohol fiber. With polyvinyl alcohol as its raw material, PVA fiber is a high strength and modulus fiber produced by a special process. It has advantage of high strength, high modulus, low elongation, good dispersing, acid and alkali resistance, wear-resistance, UV resistance and corrosion resistance. It also has good combination with cement, thus it can be used as all types of reinforcing materials. Now it is widely used in many construction field, such as dam of water project and hydraulic power, basement, harbour engineering, concrete slab and so on.

Functions:
1. Improve reinforcement of concrete.
2. Improve toughness and impact resistance.
3. Acid and alkali resistance, suitable for all cements.
4. Good dispersing.
5. Improve operating conditions.
Use instruction:
1. Mixing amount: 0.6-1kg/m3 for mortar, reinforced cement board and roof tile; 0.6-1.9kg/m3 for concrete.
2. Stirring requirement: It is no need to change the proportion of cement, sand and aggregate.
For cement concrete: crushed stones, fibers, cement and sand are put into the blender
and stir for 30 seconds, then put water and stir for 1 minute.
For asphalt concrete: Put crushed stones, sand and fibers into the blender and stir for 20
seconds. Then put the asphalt and stir up. The total time of stirring is not less than 60 seconds.
Application Field:
1. Thermal power projects, hydropower project.
2. Concrete precast, superstructure and substructure of bridge.
3. Harbour projects, such as wave wall, dike dam and slope engineering.
4. Water projects, such as dam slab, slope, floodway.
5. Water treatment system, such as concentrated pool, wastewater pool.
6.Shotcrete projects, such as inner wall of tunnel, mine.
