La description

TB-PP-Fiber, is also called engineering fiber、concrete fiber、anti-crack fiber、crack control fiber、synthetic fiber or plastic fiber, ***** 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 their microcrack caused by plastic and dry shrinkage, temperature change, etc, thereby prevent and control the happen and development of the crack and improve effectively the 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 ***** addition, the increase of the anti-infiltration of t
