China wholesale Macro Fiber - Macro Synthetic Fiber Reinforced Concrete – Kehui

Concrete is a material of a high compressive but around ten times smaller tensile strength. Furthermore, it is characterized by a brittle behavior and does not allow transferring stresses after cracking. In order to avoid brittle failure and improve mechanical properties, it is possible to add fibers to the concrete mix. This creates fiber reinforced concrete (FRC) which is a cementitious composite material with a dispersed reinforcement in a form of fibers, e.g. steel, polymer, polypropylene, glass, carbon, and others.
Fiber reinforced concrete is a cementitious composite material with a dispersed reinforcement in a form of fibers. Polypropylene fibers can be divided into microfibers and macrofibers depending on their length and the function that they perform in the concrete.
Macro synthetic fibers are typically used in structural concrete as a replacement for nominal bar or fabric reinforcement; they do not replace structural steel but macro synthetic fibers can be used to provide the concrete with significant post-cracking capacity.

Benefits:
Lightweight reinforcement;
Superior crack control;
Enhanced durability;
Post-cracking capacity.
Easily added to concrete mixture at any time
Applications
Shotcrete, concrete projects, such as foundations, pavements, bridges, mines, and water conservancy projects.
