Abstract: In the current study we analyze the behavior of Robust Self Compacting Concrete in addition of Hybrid Fibers with fine aggregate of quartz sand as 100% replacement of river sand. Apart from achieving high strength it is necessary for the structures to be more durable. In this regard laboratory tests were conducted on with the addition of hooked end steel fibers and glass fibers to check for abrasion resistance, permeability and durability studies were conducted. Experimental findings revealed that addition of hybrid fibers to specimen will result in additional loss of material when compared to specimen cast without fibers, permeability results show in the favor of specimen with fiber and durability tests indicate that percentage loss is compressive strength when immersed in 5% and 10% HCL concentration is 9.8% for without fibers and 8.5% for with fibers, and when placed in 5% and 10% H2SO4 concentration is 28.7% without fibers and 25.7% with fibers, the average loss of material for abrasion resistance test is observed to be high when fibers are added, permeability is 18ml for with fibers & 20ml for without fibers.
