METHOD OF PREDICTING FLY ASH ACTIVITY INDEX AND METHOD OF EVALUATING QUALITY OF FLY ASH

摘要

PROBLEM TO BE SOLVED: To provide a fly ash quality evaluation method which allows for easily, quickly, and appropriately predicting fly ash activity index, and a fly ash quality evaluation method that utilizes the activity index obtained thereby.;SOLUTION: A fly ash activity index prediction method involves obtaining a fly ash activity index at a fly ash age of 28 days or 91 days based on a multiple correlation relationship identified from Blaine specific surface area of the fly ash and a 45 μm sieve residue value of the fly ash.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
