The paper first introduces the properties of circulating fluidized bed (CFB) ashes (fly ash and bed ash). Then it describes the new investigations about utilization progress of them. The properties of fly ash and bed ash are not identical, so the progresses of utilization are different, too. Usually, the low carbon and high CaO bed ash can be directly used as material for construction. But the high carbon fly ash must be treated with some process before being utilized, such as hydration for cement, pelletizing for re-burning.
