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

摘要

PROBLEM TO BE SOLVED: To provide a method or the like capable of easily discriminating a high fluidity fly ash even when a flow test is not performed.SOLUTION: The discrimination method of a high fluidity fly ash of the present invention is a method of discriminating a high fluidity fly ash on the basis of an Rr value calculated using the following equation (1). Rr=R/R...(1). Here, in the equation (1), Rshows a diffuse reflectance of one wavelength optionally selected from a range of 680 to 780 nm, and Rshows an average value of the diffuse reflectances of the wavelengths in the whole range of 380 to 780 nm.SELECTED DRAWING: Figure 1
