Abstract
Due to the processing cost, there were some reports on distribution of unrefined fly ash. Hence, in this research, the possibility of fly ash quality evaluation by measuring the density of various qualities of coal ash suspensions with hydrometer. According to the experimental results, the appropriate test conditions were determined with 1,000cc capacity mass cylinder for 1,000cc of water with 100g of fly ash. From the evaluating performance of various coal ashes, based on a good correlation between fineness and quality of the coal ashes, it was possible to evaluate the quality of coal ash by measuring different density of suspension with hydrometer. In this research conditions, the suggestable measuring time of density variation was three minute for fly ash quality related with fineness.
