The results of an experimental investigation of the behavior of 9 reinforced concrete beams containing a SIFCON matrix are presented. SIFCON (slurry infiltrated fiber concrete) is characterized by a high fiber content and a very high ductility. The overall response of the beams loaded up to failure, their mode of failure, the onset of cracking, and crack development with increased load, ductility, and energy absorption are described. The effects of several variables are investigated. It is observed that the presence of SIFCON in overreinforced concrete beams leads to ductility indexes exceeding 3 times those obtained without SIFCON, and energy absorption capacities exceeding four and one-half times those obtained without it. Crack widths and spacing are more than an order of magnitude smaller than in conventional reinforced concrete, and the use of SIFCON may eliminate the need for stirrups in flexural members.
