What are the functions of high-tensile concrete fibers?

High-tensile concrete fibers are the core reinforcing material in high-tensile concrete.

High-performance concrete is a new type of fiber-reinforced material based on micro-mechanical design principles. It is composed of a matrix of cement and quartz sand, with special fibers added for reinforcement. This concrete boasts high ductility, high damage resistance, high durability, and high strength, as well as excellent crack control capabilities, hence its nickname "bendable concrete." In high-performance concrete, fibers play a crucial role in enhancing the overall performance of the material.

Currently, the fibers commonly used in high-performance concrete include polypropylene coarse fibers, polyvinyl alcohol fibers, and polypropylene fine fibers, among others. The selection and proportion of these fiber materials are crucial to the performance of high-performance concrete. For instance, polypropylene coarse fibers can enhance the crack resistance of concrete, while polyvinyl alcohol fibers can improve its durability and toughness.

High-tensile concrete fibers are an indispensable and crucial component in high-tensile concrete. Their addition significantly enhances the overall performance of concrete, bringing revolutionary changes to the construction industry.
