Regression Analysis for the Compressive Strength of Steel Fibre Reinforced Concrete

Abstract

Steel fibre has virtuous bonding properties, which when comes to compressive strength shows a better strength compared to normal concrete. In this study, the compressive behaviour of concrete when incorporating steel fibre content of 0%, 0.55%, 0.75%, 0.95%, 1.15%, 1.35%, 1.55%, 1.75%, 1.95% and 2.15% were investigated. Further, a regression equation was interpreted using a statistical software for 7 days and 28 days compressive strength of various steel fibre reinforced concrete cubes. Validation is also done with the previous research works for the Regression equation interpreted in this study.
