Steel Fibre Reinforced Concrete as a Structural Material

Steel Fibre Reinforced Concrete as a Structural Material ...

Jan 01, 2015  Fibre-reinforced concrete is the concrete with addition of short fibres targeting the improvement of the propriety of this material. Its durability is basely connected with the long-term dynamic loading. The main characteristic in that case are the critical stresses. The object of this article is steel fibre reinforced concrete (SFRC).

Fiber Reinforced Concrete - Barzin Mobasher

With better crack control characteristics than conventional steel-bar-reinforced concrete, the use of FRC generally results in improved durability over the life of the structure. The structural design of FRC sections is based on post-cracking residual strength provided by randomly oriented fibers inside the cementitious matrix.
