Investigation on Blending CFB Ash with Blast Furnace Slag as Replacement for Portland Cement Used …
In accordance with different boiler position, CFB ashes can be classified as fly ash and bed ash, and both have similar chemical compositions, with high contents of gypsum and calcium oxide. In this study, CFB ash (fly ash) is mixed with blast furnace slag (BFS) as a substitute for cement in making concrete.
