Product Description

TB-PP-Fiber, is also called engineering fiber\concrete fiber\anti-crack fiber\crack control fiber\synthetic fiber or plastic fiber, etc. It is a kind of high intensity bunchy monofilament fiber mainly made of PP by special technique.

Put TB-PP-fiber into the concrete or mortar, can effectively prevent temperature change, microcrack caused by plastic and dry shrinkage, etc, thereby prevent and control the happen and development of crack and improve effectively anti-crack\anti-infiltration\anti-concussion and anti- shock of the concrete.

They are used widely in roads\bridges\underground waterproof projects and roofings\walls\pools\basements of the industrial civil construction

*The Function of Reinforcement of TB-PP-Fiber for the Concrete.
1) Anti-crack function
TB-Fiber distributes in the concrete in 3D stereo, which reduces the stress concentration of the microcrack point, weakens or removes the tension caused by sun crack of the concrete or mortar, further prevents the happen and development of the microcrack.

For plastic concrete, TB-Fiber can support the aggregate, reduce and prevent the isolation tendency of the concrete, so lessens even prevent the happen of crack on surface.

2) The improvement of anti-infiltration performance
TB-Fiber can lessen the plastic crack of concrete effectively, and prevent the development and run-through of the crack

The evenly distributed fiber monofilament formed a support system, prevent the surface bleeding and the aggregate fall, decrease the bleeding of concrete, reduced the bleeding passage of concrete, lessened the hole rate greatly, consequently prevent infiltration of the concrete obviously.

3) The improvement of anti-freezing and thawing
TB-Fiber can decrease effectively anti-compression stress concentration in the concrete caused by several times'circulation of freezing and thawing, which prevent the further extend of the microcrack. In addition, the increase of the anti-infiltration of the concrete surely makes for the improvement of freezing and thawing.

4) The improvement of toughness and anti-shock
TB-Fiber can help to absorb the kinetic energy, which produced when the component of concrete is shocked, moreover due to the anti-crack effect of the fiber, when the concrete is shocked, the fiber can prevent the rapid extend of the inner crack, consequently increased the toughness and anti-shock of the concrete.

5) The improvement of durability
The excellent anti-crack effect of the TB-Fiber reduce the happen and development of the crack greatly.

The reduction of the inner hole rate makes the infiltration and corrosion from the water\the chemical substance\the salt of the Cl as well as other outside factors slow down, I. E. Because of the great reduction of the crack, the channel that provided by the crack which would make the function of damage and corrosion infiltrate even extend becomes less and less, which reduces the damages to the structural main bar, thereby improves the durability of the concrete.

6) The improvement of fire resistance
Adding TB-Fiber into the concrete, especially the high-strength concrete, can improve the fire resistance and the security in fire.

High-strength concrete has high compaction. In the flame, because the high pressure steam formed by heating up of free and chemical water in the concrete is difficult to escape, frequently, the component of the concrete would blowout and collapse suddenly, and cause big harm.

However the fiber concrete could avoid the blowout in fire effectively. Because when the temperature in the component of the concrete is above 165C, the PP fiber monofilament mesh that distributed around them will melt, simultaneously produce inner link channels for the escape of the high pressure steam from the concrete.
