Polypropylene PP Fiber Mesh
A. Length : Generally, the proper length of the fiber added into
concrete is 20 mm, and in the shotcrete is 10mm
B, Ratio Design. Usually the proper amount of fiber to concrete is
0.9 kg/m3 , and the water-proof layer of the bridge reauires
1.35-1.8kg/m3, and the spray concrete in the tunnel is also the
same and other materials remain the same. The ratio of Polypropylene PP Fiber Mesh and concrete can be determined by tests for special purposes. The
fiber has beter effects on the concrete with acive compound
materials, such as siicon ash, coal powder, ground slag and zeolite
powder.
C. Mixer Adoption: Double-axle horizontal compeling mixer is better
and self-dropping cylinder mixer can be used, too.
D. Mixing Process: Crushed stones,fibers and sands are put into the
mixer in succession. Afer stiring for two minutes, fiber wil fuly
spread and then add cementand water and stir normaly. The addiion
of materals aiso can be put into as usual, but the stiring time
should be properly prolonged to make fiber completely.
Application
A. Projects like concrete road, bridge, airpor road and industrial
foor which stnictly need cracking reisance. The lfespan of proiect
will be lengthened for 5-10.
B.The walls of tumels, mines, roofs and reservoir projects with
special construction. When using spray technolgy in concrete
construction,the Polypropylene PP Fiber Mesh added into.
C. River courses and dams, etc. The PP fiber can improve concrete's
resistance to crack and squirt and wear to lengthen projects'life
span.
D. Military defense works, dock banks and piers.... lt can greatly
strengthen the concrete's spurt resistance and improve projects'
safety and extend their life span.
