Cement contributes 7% of carbon dioxide in global warming in order to reduce carbon emission in atmosphere cement is partially replaced by silica fume in this project. The effects of partially replacing of cement with silica fume and fine aggregate with glass powder in concrete were studied and therefore found that some extent could be replaced which contributes in strength development. Cement was replaced with silica fume at a constant percentage of 10% and fine aggregate was replaced with glass powder at varying percentages such as 0%, 2.5%, 5%, 7.5% and 10% .The specimens were tested for compressive strength, split tensile strength and flexural strength at the age of 7 and 28 days and were compared with the results of conventional concrete. The overall test results indicated that the waste glass powder and silica fume could be utilized in concrete as a good substitute of cement and fine aggregate.
