Carbonation Treatments for Durable Low-Carbon Recycled Aggregate Concrete [PDF]
MaterialsThe use of supplementary cementitious materials and the CO2 uptake capacity of cementitious materials—including recycled concrete aggregates—not only promotes the circular economy but may also present an opportunity to increase their ecoefficiency, thus improving the shrinkage and durability properties of concretes.
