Abstract: The Mechanical properties like Compression, Flexure and Split Tensile Strength of Steel fibre reinforced Concrete (SFRC) has investigated for M35 grade of Concrete with Ground granulated blast furnace slag (GGBS) and Quarry Dust. The objective is to understand the influence in mechanical properties of shape & types of Steel fibres in the concrete and increase strength behaviours. The Concrete mixes has propotioned as per IS 10262 : 2009, In which reference and all the mixes has partially replacing 20% of Cement with GGBS and 30% of River Sand with Quarry Dust. The Combinations of blending of Steel Fibre are as like 100% Crimp & 0% hooked, 25% Crimp &75% Hooked, 75% Crimp &25 Hooked, and 0% Crimp &100% Hooked end. Totally 13 Nos. of trials are carried out in different combinations including reference mix. The workability of Concrete in all the mixes are maintained 60 – 70 mm slump by addition of PCE based Chemical Admixture 0.25% to 0.4%. The dosage is incremented 0.05% while increasing 1% of Steel Fibre so as to manage equal workability. The result from experiments has been analysed and compared with conventional specimen without fibre. The influence of fibre volume over Compression, Flexure and Split Tensile are represented graphically. The result data are shows the percentage of increase in 28 days Mechanical properties like Compressive, Flexure and Split Tensile strengths for M35 grade Concrete.
