Introduction to Steel Fiber Reinforced Concrete (SFRC)

Steel fibre reinforced concrete (sfrc) floor slabs

Steel fibre reinforced concrete is a castable or sprayable composite material of hydraulic cements, fine, or fine and coarse aggregates with discrete steel fibres of rectangular cross-section randomly dispersed throughout the matrix. Steel fibres strengthen concrete by resisting tensile cracking.

What is Steel Fiber Reinforced Concrete? - Bright Hub

Oct 10,  · Concrete is a brittle material that fractures under sudden stresses due to environmental conditions. Steel reinforced concrete can endure more stresses and has a longer life. The use of multiple types of steel fibers (round, rectangular, deformed) can significantly improve properties such as flexural strength, fatigue and impact resistance, permeability etc.
