DKM Polypropylene Fiber Mesh is made from 100% virgin PP granular by Extruding and stretching technology. The PP Fiber Mesh structured net-like appearance and connect by fiber monofilament.
The PP Fiber Mesh can highly Increase th concrete seepage and cracking resistance,improve the concrete tensile, bending and folding strength after filling into the concrete, effectively to improve the projects performance and service life.The life span of these proje
cts will be lengthened for 5-10 years.
Feature & Function:
1. The polypropylene fiber added into the concrete can effectively decrease the spray concrete's deformation rate(Walls can reduce more 8%,Roofs reduce more 12%).
2. Help to popularize the spray technology and improve the constructing efficiency.
3. Improve the Homogeneity, impact resistance, wear resistance and flexural strength of the concrete.
Application:
1. DKM-Polypropylene Fiber Mesh widely use for the concrete road, bridge, airport road and factory floor projects which strictly request for the high cracking resistance.
2. DKM-Polypropylene Fiber Mesh widely use for the walls of tunnels, mines, roofs and reservoir projects with special construction.
3. Military defense works, dock banks,river courses and dams, etc.
1. 600g/900g/1000g per Film bag.
2. 12kg per Woven bag.
3. Packing by Cartons.
Loading Capacity: 5.5 tons / 20ft container and 12 tons / 40ft container.
(1) Ration design of the fibre concrete:
Generally recommended adding amount is ≥2.7kg per sqm ( volume ratio is 0.3% ),
Reinforcement adding amount is around 5.5kg per sqm.
(2) Fiber length requirement:
50mm or 54mm for crack-resistant.
(3) Matching Ratio:
Considering the requirement of fissure-resistant, the polymer fiber is recommend to combine with the polypropylene fiber mesh with the volume ratio of 1: 1 ( 0.9kg fiber-mesh per sqm of cement concrete).
(4) Mixer Adoption:
Double-axle horizontal compelling mixer is priority.
(5) Mixing process:
Crushed stones, fibers and sands are put into the mixer in succession. After stirring for two minutes,fiber will fully spread and then add cement and water and stir normally.
The addition of materials also can be put into as common concrete,but the stirring time should be properly prolonged to make fiber completely Mixed.
(6) Shaping & Maintenance:
There is no special requirement, may along the vibrating time for 30s, The maintenance of the fibre concrete should be done same as the normal concrete.
