ABSTRACT

A large amount of industrial and agro wastes mostly end up in landfills and not much attention is given to these wastes, which cause environmental problems. Few of the industrial and agro by-products such as fly ash, sugar cane bagasse ash and silica fume act as pozzolanic materials in preparation of blended cements which provide satisfactory alternative results in waste management. The main goal of this research is to check the durability properties of carbon dioxide cured sugar cane bagasse ash concrete when exposed to marine environments. A set of different concrete mixes were prepared by partially replacing the cement with various percentages of sugarcane bagasse ash (0%, 5%, 15%, 25%) and 10% of silica fume in each mix and then these specimens were cured in water for 28 days, in CO₂ gas for 8 hours and in dry ice for 8 hours. After curing, these specimens are exposed to seawater for a period of 28 days, 90 days and 120 days, and then tests are conducted for compressive, tensile, and flexural strength. The test results indicate that replacement of cement with 5% bagasse ash & 10% silica fume showed better effective results when compared to all other percentages of replacements. The specimens cured in CO₂ gas showed similar results as that of water cured specimens while the specimens cured with dry ice showed a loss in strength.
