Abstrct: In the present experimental project, self-compacting concrete of M40 is tried using triple blended technique with condensed silica fume (CSF),as a partial replacement by weight of cement at percentage of 10% and fly ash at 20%. Steel fibres having aspect ratio of 10, 15, 20 and 25 are also used. The various proportions of steel fibres are added at 0%, 0.1%, 0.2%, 0.3% and 0.4% as percentages of the volume of concrete.The optimum replacement of cement by fly ash and condensed silica fume from which the result benefits strength and workability are studied. The specimens are tested for impact and RCPT.Based on the experimental results obtained in the present project work, conclusions are drawn on the improvement of strength properties of SCC by triple blending and employing fibres.
