Investigation of strength of concrete by replacement of sand with copper slag and cement with sugarcane bagasse ash

Abstract

This investigational study conducted to observe the potential of Sugarcane Bagasse Ash as a cement replacing material which is similar to that of Portland Pozzolana Cement and Copper slag as a fine aggregate replacement material. Seven different concrete mixes with the Bagasse Ash replacement to the Portland Pozzolana cement and copper slag replacement are (5% + 40%, 10% + 15% , 10% + 25% , 10% + 35% , 10% + 40%, 15% + 40% , 20% + 40% ) were prepared for M30 grade concrete with water to cement ratio of 0.46.The properties of these mixtures have then been assessed both at the fresh and hardened state. The results of the present study depicts that up to 10% replacement of the Portland Pozzolana Cement by Sugarcane Bagasse ash and 40% replacement of the fine aggregate by Copper slag achieved a higher compressive strength, split tensile strength and Flexural strength and at test ages of 7 and 28 days.
