    摘要： A compound and method for treating fly ash includes an amphoteric, alkyl polyglycoside, ester, derivative of triglyceride, fatty alcohol, alkoxylated fatty alcohol, alkoxylated polyhydric alcohol, and mixtures thereof, wherein the treated fly ash is incorporated into a cement admixture, and is effective in blocking absorptive carbon. Also, a method is included that reduces the amount of Portland cement by substituting up to 40 by total weight of the cement in a mixture with an equal amount of fly ash treated with an an amphoteric, alkyl polyglycoside, ester, derivative of triglyceride, fatty alcohol, alkoxylated fatty alcohol, alkoxylated polyhdric alcohol, and mixtures thereof.

    摘要： A method comprising; a step in which unburned carbon contained in coal ash is mechanically separated with a classifier; a step in which the coal ash from which part of the unburned carbon has been removed with the classifier is pulverized or disaggregated with a pulverizer; a step in which water is added to the coal ash pulverized or disaggregated with the pulverizer to obtain a slurry; a step in which a scavenger is added to the slurried coal ash; a step in which a shear force is applied to the slurry containing the scavenger to cause the scavenger to selectively adhere to the unburned carbon contained in the coal ash; a step in which a foaming agent is added to the slurry in which the scavenger has adhered to the unburned carbon; and a step in which the unburned carbon is floated on the slurry containing the foaming agent together with bubbles and is separeated.
