Abstract: Concrete is a fundamental material in the construction industry, accounting for a significant portion of the environmental impact due to its production process, primarily the emission of carbon dioxide (CO2) during cement production. Sustainable construction practices emphasize reducing environmental footprints while maintaining structural integrity. The focus of this research is on analyzing concrete mix proportions for sustainable construction, particularly through the use of alternative materials such as fly ash, slag, and recycled aggregates. These materials, when incorporated into concrete mixes, have shown promise in reducing the carbon footprint of concrete while enhancing its durability. The paper evaluates the effects of varying proportions of these alternative materials on the mechanical properties of concrete, including compressive strength, tensile strength, and durability in different environmental conditions. Additionally, the research investigates the feasibility of scaling up sustainable concrete production techniques for large-scale construction projects. The objective of this research is to provide insights into the optimal mix proportions that balance environmental sustainability with performance requirements. The research uses experimental data to assess the impact of alternative materials on the overall properties of concrete, comparing them with conventional mixes. The results indicate that sustainable mixes, particularly those incorporating fly ash and recycled aggregates, can provide comparable or even superior performance to traditional concrete mixes, with a significantly lower environmental impact. The findings suggest that sustainable concrete mix proportions could be a viable alternative for green construction practices. Furthermore, recommendations are provided for future research to optimize these mixes for different climatic conditions and construction applications. This paper provides valuable data to support the adoption of sustainable concrete solutions in the construction industry.
