Improving Concrete Sustainability and Durability by Optimization of Total Aggregate Gradations

To reduce the impact on natural resources and extend the lifetime of existing quarries, this research will attempt to reduce the large quantities of quarried rock that are currently wasted for simply not meeting current aggregate grading requirements in standard construction specifications, even though some of those wasted size fractions would improve the quality and sustainability of concrete. By optimizing aggregate particle packing, more workable and durable concretes can be produced while also reducing cement contents and therefore carbon dioxide emissions and energy consumption.
