Strength Study on Green Concrete

Abstract

Abstract: In this study, silica fume, which is finer than cement and used to substitute cement, gave concrete structures more strength and longevity. Steel fibres are utilised to improve the ductility and strength of concrete. 50% of the coarse aggregate was replaced with the 50% demolition waste aggregate. Cement with varying amounts of silica fume added (5, 10, 15, and 20%). For hardened concrete, strength tests are carried out at 7 and 28 days to assess the strength, such as compressive and split tensile. Increasing the strength parameters was made possible by the partial replacements of 10-15% of the combined use of silica fume and fly ash.
