The usage of discrete glass fiber with concrete provides enhancement the ductility and deformability. This study aims at understanding and evaluating shear behavior of discrete glass fiber concrete beams. This paper presents an experimental investigation carried out on reinforced concrete beams with discrete glass fiber mixed randomly with concrete, with 150x150mm cross section. The studied parameters included stirrups spacing (50, 75, and 100 mm) and weight percent of discrete glass fiber (0.0%, 0.75%, and 1.5%). Experimental results indicated that the shear strength of beams was significantly enhanced. Although, the number of cracks increased as a result of using discrete fiber, they became finer. Moreover, the crack propagation and its modes may be changed by using discrete fiber. The discrete glass fiber increases ductility and prevents sudden failure due to shear.

The study deals with the effect of using Slurry infiltrated fiber concrete (SIFCON) with the reinforced concrete beams to explore its enhancement to the flexural capacity. The experimental work consists of the casting of six beams, two beams were fully cast by conventional concrete (CC) and SIFCON, as references. While the remaining was made by contributing a layer of SIFCON diverse in-depth and position, towards complete the overall depths of the built-up beam with conventional concrete CC. Also, an investigation was done through the control specimens testing about the mechanical properties of SIFCON. The results showed a stiffer behavior with a significant increase in load-carrying capacity when SIFCON used in tension zones. Otherwise high ductility and energy dissipation appeared when SIFCON placed in compression zones with a slight increment in ultimate load. The high volumetric ratio of steel fibers enabled SIFCON to magnificent tensile properties.
