Shijiazhuang Cement Works fiber / polypropylene fiber manufacturers / polypropylene fiber prices $? Shijiazhuang Cement and engineering fiber production of polypropylene fiber is a polypropylene as the main raw material, the bundle of high-strength monofilament fiber made of a unique production process . Shijiazhuang cement fiber works based on customer survey found that by adding concrete or mortar can effectively control concrete (mortar) solid plastic shrinkage, drying shrinkage, micro-cracks caused by temperature changes and other factors, to prevent and suppress the crack formation and development, has greatly improved concrete crack resistance of the impermeability of impact and seismic capacity, the physical properties of polypropylene fiber cement works in fiber production in Shijiazhuang can be widely used in underground waterproof engineering, industrial civil engineering, roofing, wall, floor, pool, basement, etc. , as well as road and bridge works. 
 Shijiazhuang cement works in fiber production of cement concrete materials is currently the world's most widely used man-made building materials, but the concrete cracks due to brittle and prone to its inherent weaknesses, the ordinary high-strength concrete tensile strength is much lower than the compressive strength, easily happen brittle fracture, affecting the life of the project. With the rapid development of urban construction in China, Shijiazhuang cement fiber works, building technology innovation, high-rise buildings, elevated roadway, subway traffic and so the performance of the concrete such as: high tensile compressive strength, high toughness, high impermeability So, crack resistance, ease of construction higher requirements in the the Shijiazhuang cement works fiber in the process of transformation of concrete, fiber reinforced concrete came into being. 
 Shijiazhuang cement works in fiber production of fiber reinforced concrete, that is mixed with ordinary concrete or synthetic fibers or steel fibers or glass fiber or carbon fiber, etc., which embodies the idea of ??the design of composite materials, especially synthetic fiber reinforced concrete, not only retains The concrete of the original deposit of the characteristics of high resistance to stress, but also greatly increase the crack resistance, toughness, and impermeability, columns, plus meet the requirements of modern high-tech construction projects. Shijiazhuang Cement Works fiber production of polypropylene fiber reinforced concrete enhancements Shijiazhuang cement works in fiber production of polypropylene fibers in concrete was three-dimensional distribution, which can effectively reduce the micro-crack tip stress concentration, and can make concrete or mortar due to shrinkage tensile stress caused by weakened or eliminated, to prevent the occurrence and expansion of micro-cracks. Polypropylene fiber in the plastic concrete, the cement works in fiber production in Shijiazhuang play the role of supporting aggregate, can reduce and inhibit the segregation tendency of the concrete, and therefore reduce or even prevent the concrete surface cracks.
