Polypropylene mesh is a polypropylene fiber as raw material, made of a special production process, the appearance of multiple cross-linking of single fibers with each other from the network structure.
Polypropylene mesh fibers are put into concrete, the mixing process of single fibers by horizontal connections between the impact and tear coarse aggregate to form a monofilament of concrete per cubic there are 70 million more than in the fiber, rough edges of the tear between the fiber and concrete has an excellent bond strength, can be used for impermeable concrete cracking, reinforcing and toughening engineering.
Polypropylene mesh fiber physical parameters: the density of fiber type bundle 0.91g/cm3
6,10,19,38,54 mm equivalent diameter of 100μm length
Can be cut according to user requirements
≥ 400MPa tensile modulus ≥ 3500MPa
8-30% elongation at high acid alkaline
Melting point 160-170 ℃ 580 ℃ ignition
Polypropylene mesh fiber main functions: cracking, permeability, impact resistance, antifreeze, anti-wear and improve the toughness of concrete pavement, bridge, airport runways, factory floors and other projects that require high crack resistance. Tunnel, mine walls, roof, tanks such as the use of special methods of construction projects.
Rivers, dams and other projects. Military protection works, piers revetments, piers and so on.
Polypropylene mesh fibers for use: Select the length of normal concrete is generally used in 19mm, sprayed concrete is generally used 10mm.
Content design Generally, the dosage of 0.9kg/m3, bridge deck waterproofing layer content 0.9 ~ 1.8kg/m3, tunnel with jet mixing
Concrete Volume 0.9 ~ 1.8kg/m3.
Mixing process into the first gravel. Then put into fiber, then stir 2 minutes into the sand, so that the fibers to fully open. And then vote
Into the cement and water by conventional techniques can be mixed evenly. Conventional process can also be put into the order of construction, but the mixing stir
Mixing time should be less than 4 minutes to mix the fibers.
Forming raised no special requirements can be extended as appropriate tap for 30 seconds, finishing out the concrete surface should be slightly passivated
Further, so as not to bring out the fibers.
