In this study, silica fume (SF) was replaced with cement by the amount of 0, 2.5, 5 and 10 % in the steel fibre reinforced concrete. Concrete samples were produced by 0.50 water/cement (w/c) ratio according to C 25 and were compacted by means of table vibrator. Samples having 100×100×500 mm dimensions were produced and flexural strength test was applied to these samples. According to test results, addition of 10 % SF to steel fibre concrete caused an increase in flexural strength by 23.5 % for 28 days; 30.8 % for 90 days; 18.3 % for 120 days with respect to control sample. In the concrete in which only SF added (without steel fibre); maximum value of flexural strength was reached in the 2.5 % silica fume ratio. Decrease in the flexural strength was detected for 5 and 10 % silica fume ratios.
