CCPs include fly ash, flue gas desulfurization material (FGD), bottom ash and boiler slag and, in some cases, cenospheres. About 70% of these materials enter landfills while the remaining 30% are utilized successfully in various agricultural and construction processes
Jul 30, 2017 · The coal bottom ash was ground in a ball mill up to a Blaine fineness of 3,463 m 2 /kg, similar to that of the Portland cement (5–8% residue on 45 μ m sieve). Several coal fly and ground coal bottom ashes were mixed in the laboratory using a powder mixer. The different ground coal bottom ash and coal fly ash mixes are shown in Table 2
A new type of cemented paste backfill (CPB) was prepared by using the bottom ash (BA) from a thermal power plant as an aggregate, alkali-activated slag as a binder, and an air-entraining agent as an admixture. Based on the central composite design (CCD) response surface method, the mix ratio was optimized, and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) was …
