Cover Story: In the following study, the authors present OptiCon, an advanced mathematical model integrated into a user-friendly software tool for designing sustainable Portland Cement Concrete mixes while considering budget constraints. OptiCon optimizes mix proportions by incorporating Supplementary Cementitious Materials and Recycled Concrete Aggregate, reducing both the impact on the environment and production costs. Using Life-Cycle Assessment and Life-Cycle Cost Analysis methodologies, OptiCon evaluates multiple design scenarios to achieve optimal material dosages. With an intuitive graphical interface, OptiCon enables engineers, suppliers, and policymakers to efficiently develop eco-friendly and cost-effective concrete mixes, promoting sustainability in the construction industry. View this paper
