Abstract
In this study steel fiber reinforced concrete incorporating silica fume has been investigated, crimped steel fiber is used by volume of 1%, 1.5%, 2%, and 2.5%, silica fume content is 5% and 10% as partial replacement of cement. For better workability high range superplasticizer is used to reduce the amount of water and maintained workability. Moreover, mechanical and durability properties of SFRC are investigated, the compressive strength of steel fiber reinforced concrete is increased with increasing in content of silica fume and steel fiber at 7, 28, and 56 days. Highest result of compressive strength is achieved in the mixes with content of 2.5% of steel fiber and 10% of silica fume. The split tensile strength is conducted for all the mixes, steel fiber has significant result against peck loads, split tensile strength has significant results in all the mixes. Flexural strength of SFRC concrete has improved with content of steel fiber, increased in volume of steel fiber has increased in flexural strength. for durability properties water absorption and acid resistance tests are conducted and the results are given in the results and discussion.
