SIFCON (Slurry Infiltrated Fiber CONcrete) is a relatively new composite material utilizing steel fibers in a cement-based matrix. It differs from conventional steel-fiber-reinforced concrete (SFRC) in which the steel fibers are added directly to a typical concrete mix in the ratio of 0. 5 to 1. 5 percent by volume. SIFCON, on the other hand, starts with a bed of preplaced steel fibers in the range of 5 to 20 percent by volume. The fiber bed is then infiltrated with a low viscosity cementitious slurry. The resulting composite material possesses a very high compressive strength as well as ductility. SIFCON has the potential for many applications in the building industry.
