　　Large amounts of concrete wastes such as cement slurry waste (CSW) from concrete batching plants and fine recycled concrete aggregates (FRCA) from concrete crushing processing are now discarded to landfills.The potential of effectively recycling them merits detailed investigation.It is known that carbonation of cement based materials may improve the mechanical properties and microstructure of cement based materials with CO2 sequestration.Carbonation treatment of cement and concrete wastes would be an attractive and innovative means to fabricate value-added commercial and eco-friendly construction products.
