It is a new kind of concrete reinforcing product which is made of PP material with special technology. Its appearance is a net-like structure with many fiber monofilaments connected. When the fiber is put into the concrete, the horizontal structure of the fiber monofilament can be destroyed in the course of stirring owing to friction and rubbing, and the fiber monofilament or net-like structure will be fully stretched, thus the concrete is reinforced by a great number of polypropylene fibers. As a new kind of concrete reinforcing fiber, it becomes a hot point in the field of fiber concrete research and application after glass fiber and steel fiber.
It can be used to improve to increase the concrete cracking resistance and seepage resistance. And it can be widely used in concrete road surface, bridge surface, airport road surface, tunnel, the wall of the mine, floor, tank, river, dam, military defense, seaport, bridge pier, etc.

2、PET fiber
It is a kind of new reinforcing material made of PET by melting, extruding, quick-spinning and stretching. Its surface is specially dealt with and cut by a machine. Its appearance is beam-like structure with many monofilament fiber collecting.
It’s application includes improvement, reinforcement and connection to concrete. It can increase the concrete low-temperature resistance and prolong its life.
Besides the small thinness, high tensile strength and easily scatterred, polyester fiber has special high temperature resistance. It can be used in hot-mixing bitumen concrete projects and reinforced crack-resistance for high-tensile concrete. So it is an ideal multi-functional reinforced material.
It is mainly used in new-built bitumen concrete road surface, old bitumen concrete road improvement, road surface improvement, bridge surface bitumen concrete piece, high tensile strength concrete reinforcement.
