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.
