Abstract

The concrete industry is a major user of natural resources, which puts its sustainability in jeopardy. Considering this, this work explores how to partially replace fine aggregates in concrete production with waste glass cullets, thus addressing economic problems. With an emphasis on the M-20 mix, several weight percentages of leftover glass cullet—0%, 10%, 20%, and 30%—were used in place of fine aggregates. To assess the effectiveness of the replacement, these outcomes were then compared to those of traditional concrete. The results of this investigation validate the feasibility ofadding leftover glass cullet to replace some of the fine aggregates, up to 30% of the total weight, in the 0-1.18 mm particle size range. This not only highlights the possibility for resource optimization and waste minimization in construction procedures, but it also provides a workable answer to the sustainability issues facing the concrete sector. Stakeholders can transition to a more economically and environmentally viable paradigm in the manufacture of concrete by adopting such creative ideas. Furthermore, this study adds to the expanding corpus of studies supporting environmentally friendly building methods. It opens the door for more widespread adoption of environmentally friendly practices and promotes a more robust and environmentally friendly built environment by showcasing the viability and advantages of using waste materials in the concrete production process.
