The research aims to meet the demands of sustainable construction by using a multi-blended cement system of OPC (Ordinary Portland Cement) and different mineral admixtures in concrete. In this study, a concrete mix of M20 grade with a water-binder ratio of 0.48 is used. Glass powder and sugarcane bagasse ash are utilized as partial replacements for cement.

Glass powder, being an inert material, is a potential recycling material that can otherwise occupy landfill space for a long time. Crushed glass waste can be effectively utilized in the infrastructure industry. On the other hand, sugarcane bagasse ash is a by-product of sugar factories. The study explores the replacement of cement by glass powder ranging from 30% to 0% in increments of 5% and bagasse ash with a range of replacement from 0% to 30% in increments of 5%.

Seven different combinations of concrete mixes are studied at two different ages of concrete, specifically 7 and 28 days. The compressive strength of concrete cubes for various percentages of replacement is investigated and compared with conventional concrete to determine the optimum mix ratio. Furthermore, the flexural strength of concrete for the optimum mix ratio is analyzed, and certain durability parameters are studied in the research.
