【 摘 要 】

In the present scenario to fulfill the demands of sustainable construction, concrete made with multi-blended cement system of Ordinary Portland Cement (OPC) and different mineral admixtures is the wise choice for the construction industry. In this research work, M20 grade mix of concrete (with water - binder ratio as 0.48) is adopted with glass powder (GP) and Sugar Cane Bagasse Ash (SCBA) as partial replacement of cement. GP is an inert material, they occupy the landfill space for considerable amount of time unless there is a potential for recycling. Such glass wastes in the crushed form have a good potential in the infrastructure industry. Replacement of cement by GP from 30% to 0% by weight of cement in step of 5% and by SCBA from 0% to 30% in step of 5% respectively was adopted. In total, seven different combinations of mixes were studied at two different ages of concrete namely 7 and 28 days. Compressive strength of cubes for various percentage of replacement were investigated and compared with conventional concrete to find out the maximum mix ratio. Flexural strength of concrete for the maximum mix ratio was found out and durability parameters viz., water absorption and sorptivity were studied. From the experimental study, 20% SCBA and 10% GP combination was found to be the maximum mix ratio.
