Steel Fiber Reinforced Concrete FAQ

Steel fiber reinforced concrete is an alternative to traditional reinforced concrete for certain application areas. Steel fibers are a discontinous, 3-dimensionally orientated, isotropic reinforcement, once they are mixed into the concrete.

Mixing Fiber Reinforced Concrete

Mixing Fiber Reinforced Concrete (FRC) is different from traditional concrete in how it lacks large aggregate or pebbles and is blended with paddle mixers instead of the large drum mixers associated with a traditional concrete mix. Fiber reinforced concrete contains only fine sands, portland cement, fibers, and chemistry to accelerate its cure ...

Ultra-High Performance Fiber Reinforced Concrete

Ultra-High Performance Fiber Reinforced Concrete Structures Research on the behaviour of ultra-high performance fiber-reinforced concrete members has demonstrated that thin members can be effective without ordinary reinforcement thanks to their good deformation capacity in bending and their excellent shear strength.

Concrete Fibers

Fiber reinforced concrete is a composite material and therefore, all fibers are tested in the concrete to prove their performance. Fibers begin to function in a structural supportive manner when the concrete matrix starts to crack, just like traditional reinforcement.

Fiber Reinforced Concrete (FRC) for High Rise Construction

This is due to its flexural strength, especially for high seismic zones, as it will provide a better solution then reinforced Concrete. The main aim of this paper is to investigate the structural importance of FRC for the high rise construction.

What is Fiber Reinforced Concrete?

Fiber reinforced concrete is a type of concrete that includes fibrous substances that increase its structural strength and cohesion. Fiber reinforced concrete has small distinct fibers that are homogeneously dispersed and oriented haphazardly. Fibers used are steel fibers, synthetic fibers, glass fibers, natural fibers, asbestos fibers and carbon fibers. The characteristics of fiber reinforced ...
