Abstract:
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.
