The role of polypropylene fiber on concrete!

polypropylene fiber  to improve the freeze-thaw resistance of concrete:

The existence of polypropylene fiber  in concrete can effectively reduce the concentration of tensile stress in concrete caused by multiple freeze-thaw cycles, prevent the further development of micro-cracks, and improve its freeze-thaw resistance.

Improvement of impact resistance and toughness of concrete:

polypropylene fiber  helps to absorb the function of concrete members under impact, and can effectively enhance the impact resistance and toughness of concrete due to the crack resistance effect of the fiber.

Improvement of durability of concrete by polypropylene fiber 

Due to the good crack resistance effect of polypropylene fiber , the occurrence and development of cracks are greatly reduced, the internal porosity is reduced, and the corrosion channel of the main reinforcement of the structure is reduced, so that the durability of concrete is greatly improved and enhanced.

Improvement of high temperature resistance of concrete by polypropylene fiber 

In concrete, especially in high-strength concrete mixed with polypropylene fiber, the uniform distribution of fiber monfilaments presents a three-dimensional disorderly distribution, forming a three-dimensional network structure, when the temperature of the concrete internal components rises to 165 ° C or more, the fiber melts, forming internal connected pores for strong high-pressure steam escape from the concrete, so it can effectively avoid the fire environment burst.

Shandong Huimin Taili Chemical Fiber Products Co., Ltd. was founded in 2017, after several years of hard work, has developed into a research and development, production, sales of one-stop service of professional chemical fiber enterprises, the main products are: polypropylene high-strength silk, polypropylene color silk, polypropylene fiber, polyester fiber, polyacrylonitrile fiber, polypropylene mesh fiber, polypropylene safety rope, safety net and other chemical fiber products.
