Utilization of Waste Glass and Marble Dust Powder as Fine Aggregate and Cement Replacement in M25 Grade Concrete

Glass that a sustainable way to address environmental issues and lower construction costs is to use waste materials like shattered glass and powdered marble dust into concrete. Limited recycling markets and environmental accumulation make glass garbage, which makes up a sizable amount of the world's solid waste stream, problematic. Concrete's mechanical qualities, such as its compressive strength (9.75%), splitting tensile strength (18.38%), flexural strength (8.92%), and modulus of elasticity (5.28%) at 28 days, are improved when up to 20% of the fine aggregates are replaced with crushed waste glass, according to research. This substitution also helps with waste management. A similar alternate application for the massive amounts of trash produced during production is provided by marble dust powder, a byproduct of marble sculpting. Research indicates that after 28 days of curing, M20 grade concrete's compressive and tensile strengths are improved when up to 10% of the fine aggregates are substituted with marble dust powder. This method reduces disposal problems and encourages resource efficiency by using marble waste. In addition to addressing environmental issues, combining these waste elements into concrete produces stronger, more affordable building materials. These developments show promise for improving material performance, cutting waste, conserving natural resources, and implementing sustainable building practices.
