| titleOfInvention | Blended hydraulic cement |
| abstract | The present invention is directed to blended hydraulic cement compositionsnwhich are formed with subbituminous fly ash. In one embodiment, the cementncomposition comprises from about 0.1 wt. % to about 7 wt. % of a retardingnagent; from about 0.1 wt. % to about 4 wt. % potassium carbonate; from aboutn0.1 wt. % to about 4 wt. % citric acid; from about 0.1 wt. % to about 5 wt. %nlithium carbonate; and from about 85 wt. % to about 99.7 wt. % of ansubbituminous fly ash. In another embodiment, the cement compositionncomprises from about 0.1 wt. % to about 7 wt % of a retarding agent; fromnabout 0.1 wt. % to about 6 wt. % of an alkali source selected from the groupnconsisting of potassium carbonate, potassium hydroxide and blends thereof;nfrom about 0.1 wt. % to about 4 wt. % citric acid; from about 0.1 wt. % tonabout 5 wt. % lithium carbonate; from about 25 wt. % to about 91.7 wt. % ofna first subbituminous fly ash having a lime content; and from about 8 wt. % tonabout 60 wt. % of a second fly ash selected from the group consisting of lignitenfly ash, bituminous fly ash and scrubber material. |
