Highly workable fiber reinforced concrete for improved structural performance and constructability

Investigations of SCC and fibers

Concrete is a versatile construction material that continues to shape modern infrastructure due to its availability, ease of construction, cost-effectiveness and design flexibility. Despite its advantages, concrete's primary shortcoming lies in its weak and brittle behavior under tensile stresses. The addition of steel fibers to a concrete matrix can transform this behavior due to the ability of fibers to control and redistribute stresses after cracking. When compared to traditional concrete, steel fiber reinforced concrete (SFRC) shows several enhancements in performance, including enhanced tensile resistance, post-cracking strength, toughness and ductility. Extensive research has shown that the use of SFRC can improve the performance of reinforced concrete structural components.
