Process of producing hydraulic cement from fly ash
A hydraulic cement is prepared by reacting coal fly ash with concentrated phosphoric acid, and crushing or grinding the resulting mixture to granules or a fine powder. The reacted fly ash may be heated to reduce the water of hydration before final crushing or grinding. The resulting hydraulic cement...

| description | A hydraulic cement is prepared by reacting coal fly ash with concentrated phosphoric acid, and crushing or grinding the resulting mixture to granules or a fine powder. The reacted fly ash may be heated to reduce the water of hydration before final crushing or grinding. The resulting hydraulic cement may be mixed with sand and/or gravel aggregate to prepare mortar or concrete mixes for applications similar to Portland cement, or the fly ash cement may be mixed with soils to stabilize them. |
