Abstract—Concrete is a versatile material extensively used in construction applications throughout the world. Properly placed and cured concrete exhibits excellent compressiveforce-resisting characteristics In the present experimental investigation a mix design high strength concrete of M60 & M80 is tried using triple blending technique with ternary blend of condensed silica fume and metakaolin as partial replacement by weight of cement at various blended percentages ranging between 5% – 15% with steel fibers having aspect ratio of 50. The various proportions of steel fibers are added at 0.5%, 0.75%, 1.0%, 1.25% and 1.5% as total fiber percentages. The workability is measured for its consistency using compaction factor method. The present work is on finding the optimum replacement of cement by metakaolin, condensed silica fume and ternary blend of condensed silica fume and metakaolin from which maximum benefit in various strengths and workability of the mix can be obtained. The results of fiber reinforced specimens with various percentages of ternary blend are compared with control specimens to study the behavior of FRC properties with various percentages of the blends as partial replacement by weight of cement. Sufficient number of cubes, cylinders and beams were cast. The cast specimens were tested for the change in compression, tension and flexural strength at 7 & 28 days for M60. The cast specimens were tested for the change in compression, tension and flexural strength at 28 days for M80. It is concluded that specimens with total fiber content of 1.5% showed better strength in all proportions and blend proportion of 10% condensed silica fume and 5% metakaolin showed maximum strength in compression, tension and flexural.
