TB-PP-Fiber, is a kind of high intensitybunchy monofilament fiber mainly made of polypropylene by specialtechnique.

Put TB-PP-fiber into the concrete ormortar, can effectively prevent temperature change, microcrackcaused by plastic and dry shrinkage, etc, thereby prevent andcontrol the happen and development of crack and improve effectivelyanti-crack, anti-infiltration, anti-concussion and anti- shock ofthe concrete.

It is used widely in roads, bridges,underground waterproof projects and roofs, walls, pools, basementsof the industrial civil construction. 

Function

Anti-crackfunction

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

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

Improvement ofanti-infiltration performance

TB-Fiber can lessen the plastic crack ofconcrete effectively, and prevent development and run-through ofcrack.

The evenly distributed fiber monofilamentformed a support system, prevent the surface bleeding and aggregatefall, decrease the bleeding of concrete, reduced the bleedingpassage of concrete, lessened the hole rate greatly, consequentlyprevent infiltration of concrete obviously.

Improvement ofanti-freezing and thawing

TB-Fiber can decrease effectivelyanti-compression stress concentration in the concrete caused byseveral times` circulation of freezing and thawing, which preventthe further extend of microcrack. In addition, the increase of theanti-infiltration of concrete surely makes for improvement offreezing and thawing.

Improvement of toughnessand anti-shock

TB-Fiber can help to absorb kinetic energy,which produced when the component of concrete is shocked, moreoverdue to the anti-crack effect of fiber, when the concrete isshocked, the fiber can prevent rapid extend of inner crack,consequently increased the toughness and anti-shock ofconcrete.

Improvement ofdurability

The excellent anti-crack effect of TB-Fiberreduce the happen and development of the crack greatly.

The reduction of inner hole rate makes theinfiltration and corrosion from water, chemical substance, salt ofCl as well as other outside factors slow down, i.e. because of thegreat reduction of crack, the channel that provided by crack whichwould make the function of damage and corrosion infiltrate evenextend becomes less and less, which reduces the damages tostructural main bar, thereby improves the durability ofconcrete.

Improvement of fireresistance

Adding TB-Fiber into concrete, especially thehigh-strength concrete, can improve the resistance and security infire.

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

However the fiber concrete could avoid theblowout in fire effectively. Because when the temperature incomponent of concrete is above165℃,the PP fiber monofilament meshthat distributed around them will melt, simultaneously produceinner link channels for the escape of high pressure steam fromconcrete.
