In this paper, silica fume and fly ash class F was used as a supplementary cementing material in cement mortars to evaluate several mechanical properties of SIFCON (Slurry Infiltrated Fibrous concrete) in the way of flexural, compressive and splitting strength which were determined using the standard test method, the impact load resistance was determined using a fabricated instrument described in body paper. plate specimens with dimension of 450mm×100mm×40mm were cast with micro steel fiber of 6% volume fraction were tested under impact load for assessment with references plates at 90 days of age. From the results of the outcome it was found that the performance of conventional mortar is much less than SIFCON specimens. The compressive, splitting, flexural strength and impact resistance for conventional mortar and SIFCON specimens were investigated, a significant development in impact resistance for SIFCON mix at first crack and failure, also the energy demand for the whole failure was which is increased by 9.97 times compared with the conventional mortar. Thus, this present paper displays that SIFCON can be utilized as a powerful option in different development purposes or where the concrete or natural steel fiber reinforce concrete can't execute surprisingly/needed or in situations where such greater strength is imperative and essential.
