METHOD FOR REFORMING UNBURNT-CARBON-CONTAINING FLY ASH, SYSTEM FOR REFORMING UNBURNT-CARBON CONTAINING FLY ASH, AND METHOD FOR PRODUCING FLY ASH FOR CONCRETE ADMIXTURE
There is provided a method for reforming unburned carbon-containing coal ash of the present invention, including: a receiving process of measuring L value and b value of unburned carbon-containing coal ash in a Lab color order system and sorting unburned carbon-containing coal ash of which the L value is 54 or more and the b value is 2 or more and 10 or less; and a classifying process of classifying the unburned carbon-containing coal ash sorted in the receiving process under a condition that a residue on a 45 μm sieve of reformed coal ash which has been reformed by classification is 8% by mass or less.
