  Infrastructure Development For A Country Is A Principle Development And Concrete Plays A Vital Role. Concrete Is The World’s Largest Consuming Material In The Field Of Construction. From Time Immemorial Research Over Concrete Has Been Going On To Enhance Its Performance And Strength. Nowadays, Most Concrete Mixture Contains Supplementary Cementious Material (SCM) Which Forms Part Of The Cementitious Component. These Materials Are Majority By-products From Other Processes. The Main Benefits Of SCMs Are Their Ability To Replace Certain Amount Of Cement And Still Able To Display Cementitious Property, Thus Reducing The Cost Of Using Portland Cement. The Fast Growth In Industrialisation Has Resulted In Tons And Tons Of By-product Or Waste Materials, Which Can Be Used As SCMs Such As Silica Fume, By Adding Steel Fibers And Carbon Fibers Etc. The Use Of These By-products Not Only Helps To Utilize These Waste Materials But Also Enhances The Properties Of Concrete In Fresh And Hydrated States. This Study Focuses On The Experimental Investigation Of Partial Replacement Of Cement With Ground Granulated Blast Furnace Slag (GGBS) In Hybrid Fibre Reinforced Concrete (HFRC) Using Steel And Carbon Fibres. The Main Objective Is To Evaluate The Mechanical And Durability Properties Of Concrete With Varying Percentages Of GGBS. Cement Is Partially Replaced With GGBS At Different Proportions Such As 0%, 20%, 40%, And 60%. Hybrid Fibres Are Added To Improve Tensile Strength, Crack Resistance, And Ductility. Steel Fibres Enhance Load-carrying Capacity, While Carbon Fibres Help In Controlling Micro-cracks. The Experimental Program Includes Tests On Compressive Strength, Split Tensile Strength, And Flexural Strength. The Results Indicate That GGBS Improves Long-term Strength And Durability, While Hybrid Fibres Significantly Enhance Mechanical Performance. The Study Concludes That GGBS-based Hybrid Fibre Reinforced Concrete Is A Sustainable And High-performance Construction Material.
