Abstract

Development industry is associated either coherently or correspondingly with the cement industry. In concrete, it assumes the part of generally huge, adaptable and energy consuming material. Thus, the replacement of the cement with other cementation material is able to straightforwardly affect the cost of concrete. Therefore, with the secondary cementations material, the flyash has been replaced with cement in different proportions. Replacing cement with flyash will overcome its dumping issues and it will decrease the cost of concrete. It affects strength of the concrete and makes it sustainable. In this investigation, cement has been replaced by flyash mixed with steel fiber reinforced concrete and making specimens to test the compressive, flexural and tensile strength. Steel fibers were added in various percentages, to check the impact of it on the mechanical properties of flyash mixed with steel fiber. The proportion of steel fiber is 0.5%, 1%, 1.5%, 2% and 2.5% and the flyash used to replace cement is 20%, 30%, 40% and 50%. To determine the workability of flyash steel fiber reinforced concrete, slump test was also performed.
