Hybrid fibre reinforced concrete is procurement from the grouping of diverse types of fibres, which fluctuate in the substance of properties, keep on bond mutually when supplementary in concrete and retain their identities and properties. The combination of fibres, often called hybridization, concrete is looking into for an M50 grade. Hybrid fibre composites were cast by replacing cement with 25% 30% and 35% fly ash and 5%, 10% and 15% of micro silica. A stable percentage of 0.5% Steel and 0.5% polypropylene fibre are used for all three mixes. The density of concrete increases by adding micro silica and steel fibre to concrete which imparts the strength of concrete, Compressive, Spilt tensile and flexural strength of HFRC of mix-2 increases up to 8.76%, 8.12%, and 4.33% respectively that of the normal concrete mix. The boost in steel fiber percentage results only increase in tensile strength. The mix-2 (MS 10%+FA30%) shows superior outcome signifying most favorable substitution to the cement. .
