FLUIDITY EVALUATION METHOD OF FLY ASH, HIGH FLUIDITY FLY ASH, AND FLY ASH MIXED CEMENT

摘要

PROBLEM TO BE SOLVED: To provide a fluidity evaluation method of fly ash capable of easily and accurately evaluating the propriety as high fluidity fly ash.SOLUTION: The fluidity evaluation method of fly ash of the present invention includes a method or the like of evaluating the fluidity of the fly ash on the basis of the area circularity of fly ash particles and the projection area of the fly ash particles. The high fluidity fly ash of the present invention is fly ash that has been evaluated as the high fluidity fly ash using the fluidity evaluation method. The fly ash mixed cement of the present invention is cement produced by mixing cement and the high fluidity fly ash.SELECTED DRAWING: Figure 1
