Process for making a blended hydraulic cement |
摘要 |
The present invention is directed to processes for making blended hydraulic cement compositions. In one embodiment, the process includes the steps of: providing from about 85 wt. % to about 99.7 wt. % of the total composition of a subbituminous fly ash; separating out about a 10% portion of the fly ash; adding from about 0.1 wt. % to about 7 wt. % of the total composition of a retarding agent, from about 0.1 wt. % to about 4 wt. % of the total composition of citric acid, and from about 0.1 wt. % to about 4 wt. % of the total composition of potassium carbonate to the 10% portion; and blending the remainder of the ash with the 10% portion to create a blended hydraulic cement composition.
