However, SFCRC20 falls in Zone A (3.66-4.58 km/sec) which could be suggested as a limited ratio of rubber aggregate incorporated in steel fiber reinforced concrete
. For fibrous concrete, the inclusion of crumb rubber aggregate improved its capacity to absorb the transit velocity, which can be considered as a good material for sound absorption and with suitable strength to resist structural loading.

The inclusion of the fibers into the concrete mix influence its workability (Hannat, 1978; Swamy, 1974) ACI committee report in 1996,reported that in the typical ranges of volume fractions used for steel fiber reinforced concrete
(0.25 to 1.5 volume present),the addition of steel fiber reduced the measured slump of the composite as compared to plain concrete in the range of 25 to 102mm.Incorporation of super plasticizer is essential to maintain good workability (120-150mm).Steel fiber improves the ductility of concrete under all modes of loading.
This recommendation was chosen because it does not require previous knowledge of the tensile stress-strain relationship of steel fiber reinforced concrete
. In this recommendation, shear strength provided by concrete and fibers (Vc and Vcf) was calculated separately.
