PROBLEM TO BE SOLVED: To provide a particle size distribution analysis method and a quality control method for construction material capable of improving accuracy of particle size distribution analysis.SOLUTION: A particle size distribution of construction material which is an analysis object is analyzed by performing multiple regression analysis using construction material whose particle size distribution is known to create a regression equation for each particle size, substituting an explanatory variable calculated from an image analysis result of the construction material which is an analysis object for the created regression equation, calculating an analysis object mass ratio for each particle size, and using the calculated analysis object mass ratio for each particle size.SELECTED DRAWING: Figure 3 |
