Polypropylene Twisted Bundle Fiber Reinforced Concrete

Polypropylene Twisted Bundle Fiber Reinforced Concrete

Polypropylene twisted bundle fiber reinforced concrete is widely used in concrete engineering.Bundle twisted PP fiber is developed for replacement of steel fiber.It has more advantages in concrete structures,except the characteristics of ordinary steel fiber.

With polypropylene as its raw material,it is producted by special drawing twisting and surface treatment.It has good acid and alkail resistance.Twisted bundle pp fiber has high strength,Polypropylene twisted bundle fiber has very good corrosion resistance and anti-aging ability.Excellen tensile,easy dispersing with concrete,and no damage to the mixing equipment.Convenience for construction,it can reduce the construction difficulty and  time  of concrete struction,improve engineering efficiency.

Technical Parameter of Polypropylene Twisted Bundle PP Fiber:

Applying Instruction:

1、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、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.

3、Package:1/kg per bag,may packed according to ratio with PP Fiber mesh.

Application with Twisted Bundle PP Fiber:

1、Be suitable for the  industrial workshop，ware house and parking lot.

2、In crease cracking resistance on surface of airpot,underground.

3、Improve the cracking resistance in large scale of cement concrete.
