concrete.Concrete surface treatment is one of the effective protection methods to improve the durability of concrete.CO2 treatment produced a carbonated layer,but increased the compressive strength,and effectively reduced the water permeability,water-vapor transmission and chloride migration.The cement ...
The production of aggregates can be based on the carbonation of Mg- or Ca-rich silicates, iron slag, and coal fly ash75. The debris after construction demolition, the crushed, recycled aggregate gathered from concrete can be subjected to carbonation and recycled as carbonated aggregates to ...
