Abstract:

The objective of this subtask was the development of flexural material properties for slurry infiltrated fiber concrete SIFCON. Included in this report are the procedures used, the material properties data base, all test results, relationship plots, and general conclusions. Methods for testing SIFCON in shear and tension were also investigated. Slurry Infiltrated Fiber CONcrete, designated SIFCON, is a new composite material utilizing steel fibers in a cement-based matrix. It differs from conventional fiber-reinforced concrete in which the steel fibers are added to a typical concrete mix in a 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 22 percent by volume. The fiber bed is then infiltrated with a low-viscosity cementitious slurry. The resulting composite material possesses very high strength as well as ductility. In addition it has been demonstrated that SIFCON is highly resistant to dynamic loads such as blast pressure and ballistic penetration.
