An Experimental Study on Steel-Nylon Hybrid Fibre Reinforced Concrete for M-25 Grade

Concrete Plays A Vital Role As A Construction Material In The World. But The Use Of Concrete As A Structural Material Is Limited To Certain Extent By Deficiencies Like Brittleness, Poor Tensile Strength And Poor Resistance To Impact Strength, Fatigue, Low Ductility And Low Durability. Critical Investigation For M-25 Grade Of Concrete With Water Cement Ratio of 0.43 To Study The Compressive Strength, Flexural Strength, Split Tensile Strength Of Fibre Reinforced Concrete (Frc) Containing Fiber Of 0.75% Volume In Different Proportions. End Hook Steel Fibres(Novocon He0630) With Aspect Ratio Of 50 & Nylon 6 Fibre With Aspect Ratio Of 150 were used. The Total Volume Of Fiber Was Taken 0.75% Of Total Volume Of Concrete With Steel-Nylon Proportion Of 100-00%, 75-25%, 50-50% & 25-75%. A Result Data Obtained Has Been Analyzed And Compared With A Control Specimen (0% Fiber). Result Data Clearly Shows Compressive Strength, Flexural Strength And Split Tensile Strength For M-25 Grade Of Concrete For 7 & 28 Days With Graphical Representation.
