Carbonation rate and reinforcing steel corrosion of concretes with recycled concrete aggregates and supplementary cementing materials

Because of the significant environmental impact that the concrete production causes, and as sustainability contribution for this industry; presently some improvements are being implemented in its durability and its components are been replaced for alternative recyclable materials. Concrete carbonati...
