Optimizing concrete durability: modeling acid resistance with recycled aggregates for sustainable construction in Cameroon

This study investigates the physical and mechanical properties of concrete made with recycled aggregates, focusing on their reaction to acid attacks for sustainable construction in Cameroon. Despite initial challenges, such as lower density and higher water absorption in recycled aggregates, optimized concrete formulations can compensate, achieving comparable strengths to traditional concretes after extended curing periods. Recycled aggregates showed greater susceptibility to acid attacks, necessitating advanced protective strategies. Polynomial regression models enhanced the understanding of compressive strength evolution and degradation, proving vital for engineering predictions. The research advocates for the optimized use of recycled materials in construction, adhering to sustainability standards and contributing to environmental protection. Continued advancements in protective treatments and concrete formulations are essential for broadening the application of eco-friendly building materials.
