Method of Preparing Admixture and Artificial Light-weight Aggregates by Hydration of Flyash Produced by Fluidized Bed Combustion

摘要

The present invention relates to a method for producing an admixture by hydration of a fluidized bed fly ash, and is characterized in that a fluidized bed fly ash containing a large amount of CaO generated in a fluidized bed boiler of a thermal power plant is hydrated alone or mixed with an inorganic material and a sludge , It has the effect of satisfying the same or higher quality as compared with the conventional pulverized fly ash, and the aggregate manufactured by using this admixture is satisfactory to the KS standard (KS F 2534) .
