An Experimental Study on Properties of Ternary Blended Steel Fibre Reinforced Concrete

This research presents the mechanical properties of ternary blended concrete incorporating steel fibres. Cement was replaced by GGBS (Ground Granulated Blast furnace Slag) and Nano Silica. Replacing with GGBS 35% and Nano silica 1% was found to give the optimum combination. Hooked end steel fibres of aspect ratio 75 in different volume fractions of 0.5%, 1%, 1.5%, 2% were added to the ternary blended concrete. Compressive strength test, Flexural strength test, and elasticity modulus test were conducted to study the mechanical properties of ternary blended concrete. The test results show that micro reinforcement concrete with GGBS and Nano silica execute well compared to the control sample. The addition of steel fibres improves the ductility and performance of concrete. (C) 2021 INT TRANS J ENG MANAG SCI TECH.
