Abstract: Self-compacting concrete (SCC) is known to be brittle and can easily crack under low levels of tensile force just like the ordinary concrete. This behavior of brittleness can be overcome by using randomly oriented short discrete fibers. This study investigates the influence of different sizes and dosages of polypropylene fibers, steel fibers and basalt fibers on the fresh properties (Slump flow,T500 time, V-funnel flow time, L-box passing ability which are used to measure the workability) and the hardened properties (compressive strength test, splitting tensile strength test) of Self-compacting concrete. Overall, the addition of fibers generally decreases the workability of the fiber reinforced self-compacting concrete (FRSCC) and doesn't significantly increase the compressive strength because of that fibers may affect the Interfacial Transition Zone (ITZ) between the aggregate and the paste, steel and Polypropylene fibers can produce voids inside the paste form while the basalt fiber will absorb the mixing water and hence reduce the compressive strength.
Keywords: self-compacting concrete, fibers, fresh properties, hardened properties, compressive strength.
