摘要
The present invention relates to a method for manufacturing a concrete admixture using fly ash produced in a circulating fluidized bed (CFB) boiler of power plants, more specifically, and to a method for manufacturing a concrete admixture using the fly ash which is produced in the CFB boiler of power plants including large amount of CaO and is gone through hydration and carbonation. According to the method using the fly ash for manufacturing the concrete admixture of the present invention, the environmentally friendly concrete admixture is manufactured with chemical stability. A problem that the carbonation of the fly ash makes a particle-size smaller is solved.
