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 thickness. Different types of fiber are used based on the function that they perform in the concrete.

Fiber-reinforced concrete or fibre-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented. Fibers include steel fibers, glass fibers, synthetic fibers and natural fibers – each of which lend varying properties to the concrete. In addition, the character of fiber-reinforced concrete changes with varying concretes, fiber materials, geometries, distribution, orientation, and densities.

Blends of both steel and polymeric fibers are often used in construction projects in order to combine the benefits of both products; structural improvements provided by steel fibers and the resistance to explosive spalling and plastic shrinkage improvements provided by polymeric fibers.

In certain specific circumstances, steel fiber or macro synthetic fibers can entirely replace traditional steel reinforcement bar (“rebar”) in reinforced concrete. This is most common in industrial flooring but also in some other precasting applications.

3 types of AJS Fiber Reinforced Concrete :

• Polypropylene Mono Filament
• Polypropylene Fibrillated
• Synthetic Macro Fiber
