Polypropylene Twisted Bundle Fibers 38mm 54mm Length

Polypropylene Twisted Bundle Fibers 38mm 54mm Length

The polypropylene twisted bundle fibers are widely used with the continuous development of construction engineering .The polypropylene twisted bundle fiber is made of polypropylene as the main raw material through special parallel drawing and twisted molding process and surface treatment. Alternatives developed for steel fibers.Twisted bundle pp fiber is a material between steel fiber and synthetic fiber. When the amount of polypropylene twisted fiber is high, the early anti-cracking effect on the concrete is significant, which can replace the steel fiber or steel wire mesh, increase the toughness of the concrete, and improve the ability to resist temperature stress or cracking.

The main characteristics of polypropylene twisted bundle fibers 38mm 54mm Length as follwos:

Twisted bundle PP fiber has good disapersion and adhesion to the cement matrix,which can significcantly improve the toughness of concrete.

PP twisted bundle fiber plays the role of reinforcement and bridging in concrete to enhance the crack resistance,bending tensile strength and bending toughness of concrete.

Improve the resistance of concrete to temperature stress or cracking,and improve the ease of fibers in concrete.

Packaging instruction of twisted bundle fibers:

1kg per bag,may packed according to ratio with PP fiber mesh,or pack it according to the customer's requirement.

Polypropylene twisted bundle fibers' applying instruction:

1、Product dosage :no less than 3kg/cubic meter of concrete for high crack level(volume ratio:0.3%);for general level,it can use compound fiber of 0.8kg twisted bundle PP fiber and 0.4kg PP fiber mesh.

2、Convenience for construction stirring requirment:crusted stones,fibers and sands are put into the mixer in succession.After stirring for 2 mintues,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 more than 4 mintues to make fiber completely mixed.

Application of polypropylene twisted bundle cement fibers:

Polypropylene twisted bundle fibers are mainly used for concrete panel structures, such as highway pavement, bridge pavement, airport pavement, etc.

Polypropylene twisted bundle PP fibers  are suitable for reinforced and partially reinforced concrete structures, such as industrial building floors, warehouse floors, etc.

Twisted bundle PP fiber  is also used in spray engineering, especially for highways and tunnels.
