SUPPRESSION OF ANTAGONISTIC HYDRATION REACTIONS IN BLENDED CEMENTS
Method for suppressing antagonistic hydration reactions in Portland fly ash cement involves the use of unponded fly ash that is pre-hydrated, preferably as an aqueous slurry wherein fly ash, preferably having an alkaline earth metal oxide of at least 10% by weight, is soaked, whereby the hydration r...

| description | Method for suppressing antagonistic hydration reactions in Portland fly ash cement involves the use of unponded fly ash that is pre-hydrated, preferably as an aqueous slurry wherein fly ash, preferably having an alkaline earth metal oxide of at least 10% by weight, is soaked, whereby the hydration reaction of the resultant mixed fly ash and cement is accelerated when these components are mixed together with water to hydrate the cement. Blended Portland cement/fly ash compositions of the invention will also have higher early strength as well as shorter set time compared to untreated blends. |
