Polypropylene Fiber Fibrillated Mesh

Introduction:

Briture PP Fiber Fibrillated Mesh form is made of 100% virgin homopolymer polypropylene with form of mesh, it is mainly used for concrete and mortar reinforcement, anti-cracking.

Function:

Applying Instruction:

1. Length : Generally, the proper length of the fiber added into concrete is 20 mm, and in the spray concrete is 10mm.

2. 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.

3. Mixer Adoption: Double-axle horizontal compelling mixer is better and self-dropping cylinder mixer can be used, too.

4. 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 usual, but the stirring time should be properly prolonged to make fiber completely mixed.

5. 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 2-3minutes after the addition of polypropylene fiber-mesh.
