Function
Anti-crack
PP-Mono-Fiber distribute in concrete in the form of 3D, that could reduce stress concentration of micro-crack point, weaken or remove the tension caused by sun crack of concrete or mortar, further prevent micro-crack from happening and developing.
Improve anti-infiltration performance
The evenly distributed fiber monofilament forms a support system, that prevents surface bleeding and aggregate falling, decreases bleeding of concrete, lessens hole rate greatly, consequently prevents infiltration of concrete obviously.
Improve anti-freezing and thawing
PP-Mono-Fiber could effectively decrease anti-compression stress concentration caused by several times’ circulation of freezing and thawing in concrete, and prevent further extending of micro-crack.
Improve toughness and anti-shock
PP-Mono-Fiber could help to absorb the kinetic energy produced when component of concrete is shocked. Due to anti-crack effect of fiber, when concrete is shocked, fiber could prevent rapid extending of inner crack, consequently increase toughness and anti-shock of concrete.
Improve durability
Excellent anti-crack function of PP-Fiber could decrease inner hole rate and corroding channels, reduces damages to concrete then improves durability of concrete.
Improve fire resistance
When temperature in concrete raises above 165℃,PP fiber monofilament mesh will melt, simultaneously produces inner link channels to help high pressure steam escape from concrete, consequently prevent bursting in fire
Application
Put PP-Mono-fiber into concrete or mortar, could effectively prevent micro-crack caused by temperature change,plastic and dry shrinkage.It is widely used in roads, bridges, underground waterproof projects and roofs, walls, pools, basements of civil construction industrial and other construction projects.
