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.
