PP Fiber Fibrillated Mesh Form 350M The Optimal Solution for Cracking Resistance

PP Fiber Fibrillated Mesh Form 350M

Introduction:

Briture PP Fiber 350M is made of 100% virgin homopolymer polypropylene with form of mesh, it is mainly used for concrete and motar reinforcement,anti-cracking

Function:

Increase seepage resistance Prolong endurance Improve steel protection

Increase cracking resistance Increase fire resistance Strengthen spurt & fatigue

Improve tensile, bending & folding strength Strong acid & alkali resistance and good endurance

Improve plastic deformity

Applying Instruction:

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 0.9kg/m3, and the water-proof layer of the bridge requires 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 fiber and concrete can be determined by tests for special purposes .The fiber has better effects on the concrete with active compound materials, such as silicon ash, coal powder, ground slag and zeolite powder.

C. Mixer Adoption: Double-axle horizontal compelling 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. After stirring for two minutes, fiber will fully spread and then add sement and water and stir normally. The addition of materials also can be put into as usual, but the stirring time should be properly prolong to make fiber completely.

E. Stirring Time: The purpose of the stirring is to make fiber fully spread into monofilament or the net fully spread, so generally the stirring time is 2-3 minutes after the addition of polypropylene fiber-mesh.

Application:

A. Projects like concrete road, bridge, airport road and industrial floor which strictly need cracking resistance. The lifespan of projects will be lengthened for 5-10.

B. The walls of tunnels, mines, roofs and reservoir projects with special construction. When using spray technology in concrete construction, the PP fiber 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... It can greatly strengthen the concrete's spurt resistance and improve projects' safety and extend their life span.
