Polypropylene-Fiber-Filament(for the concrete)

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

High-strength concrete has high compaction. In the flame, because the high pressure steam formed by heating up of the 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.

Adding TB-Fiber into the concrete, especially the high-strength concrete, can improve the fire resistance and the security in fire

6)       The improvement of fire resistance

The reduction of the inner hole rate makes the infiltration and corrosion from the waterthe chemical substancethe 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.

The excellent anti-crack effect of the TB-Fiber reduced the happen and development of the crack greatly

5)       The improvement of durability

TB-Fiber can help to absorb the kinetic energy produced when the component of the 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.

4)       The improvement of toughness and anti-shock

TB-Fiber can decrease effectively anti-compression stress concentration in the concrete caused by several timescirculation of freezing and thawing, which prevented the further extend of the microcrack.In addition, the increase of the anti-infiltration of the concrete surely makes for the improvement of its freezing and thawing

3)       The improvement of anti- freezing and thawing

The evenly distributed fiber monofilament formed a support system, prevented the surface bleeding and the aggregate fall, decreased the bleeding of the concrete, reduced the bleeding passage of the concrete, lessened the hole rate greatly, consequently made anti-infiltration of the concrete increased obviously

TB-Fiber can lessen the plastic crack of the concrete effectively, and prevent the development and run-through of the crack

2)       The improvement of anti-infiltration performance

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

TB-Fiber distributes in the concrete in 3D stereo, which reduces the stress concentration of the point of the microcrack, weakens or removes the tension caused by the sun crack of the concrete or mortar, further prevents the happen and development of the microcrack

The Function of Reinforcement of TB-Polypropylene-Fiber for the Concrete

FRHPC, that is, adding synthetic fiber or steel fiber or glass fiber or carbon fiber etc. into the ordinary concrete, which embodied the logos of the design of composite material.Especially the synthetic fiber reinforced concrete, not only remain the high anti-compression the concrete inhered, but also reinforce its anti-crack, anti-infiltration and toughness, that make it meet the demand of nowadays high and new construction better.

With the rapid development of the city construction of our country and the continuous innovation of the technique of architecture, the high-rise buildingsthe skywaysthe underground traffic makes requests to the performance of the concrete, e.g., high anti-stretch and anti-compressionhigh toughnesshigh anti-infiltration and anti-crackeasy to construct and so on, as a result, the FRHPC arised.

The cement concrete material is the most widely-used man-made construction material nowadays. But it tends to produce crack as a result of its brittleness, and the anti-stretch intensity of the ordinary high-strength concrete is far lower than its anti-compression intensity, so the brittleness damage easily happen, which will influence the lifetime of the project.

 The General Introduction of the Fiber Reinforced High Performance Concrete(FRHPC)

Polypropylene-Fiber-Filaments are mainly mixed into the cement concrete to improve the performance of the concrete.
