Abstract

This study is aimed at investigating the compressive strength of concrete using Sugarcane Bagasse ash (SCBA) as a replacement for cement in concrete using two grades of concrete; grade 20, and 30 respectively. Sugarcane bagasse ashis the waste product of the combustion of bagasse for energy in sugar factories and are also bye-products of agricultural waste, sugar cane bagasse ash are disposed in landfill and are now becoming an environmental concern. The concrete cube cast was; control (0%) 2%, 4%, 6% and 8% respectively, the cube was cast, cured and tested at 7days, 14days, and 28days. Although, the results of this study have shown a significant reduction in compressive strength of concrete utilizing SCBA than normal concrete, it can be concluded that, optimum amount of sugarcane bagasse ash that can be replaced with cement is 6% by weight without any admixtures.
