| dc.description.abstract | Cement is the primary ingredient in concrete, used to create pastes that strengthen the bond. The emission of CO2 into the atmosphere has been considerably impacted by the manufacture of cement. Additionally, a lot of energy is required for production. On the other hand, wastes like sugarcane bagasse ash and cattle bones seriously harm the environment. Cattle bone wastes from slaughterhouses and sugarcane bagasse ash wastes collected from Wunji sugar factory have been used in this study. The main objective of the study was to use these waste products as a partial replacement for cement. The cattle bone was burned at a temperature of 900°c to produce the appropriate cementitious property of cattle bone ash. The temperature at which sugarcane bagasse ash burned was 700 o C. In this study, a qualitative research methodology was applied. Characterization of the SBA and CBA materials has been done using x-ray florescence (XRF). Since several researches consistently employed the same percentage, this research tends to use an equal amount of bagasse and cattle bone ash was added to the regular concrete mix after carrying out trial mixes for the amount of SBA and CBA and applied to the replacement percentages of 5%, 10%, 15%, and 20% by weight of cement. The results of compressive and tensile strength of cured concrete demonstrate that it is stronger when up to 10% of the cement is replaced with a mixture of bagasse and cattle bone ash. Concrete strength can be increased by adding combined bagasse and cattle bone ash to concrete. Additionally, using combined SBA and CBA in the cement will enhance the early strength attainment as a result of increasing the tricalcium silicate (C3S) as the percentage increases from 0 to 20, while the compound dicalcium silicate (C2S) which is responsible for the long-term strength of concrete decreases which results in the almost small change of concrete strength as the age of concrete increases. Micro-structural of concrete using XRD, SEM, FT-IR, TGA and DTA has been analyzed for a curing age of 28 days. The microstructural analysis of cement paste at 28 curing ages of concrete of BCBA-10 shows improved (C-S-H gel) which enhances and improved the compressive and tensile strength of concrete.
