Carbon microfibers, a type of advanced reinforcement material, are increasingly used in the construction industry to enhance the properties of cement and concrete. These tiny fibers, typically a few micrometers in diameter, are derived from carbon or graphite materials and are known for their high strength and stiffness. When added to concrete, carbon microfibers improve tensile strength, reduce cracking, and increase durability, making the composite material more suitable for applications where mechanical and environmental stresses are significant.
