PROBLEM TO BE SOLVED: To provide an evaluation method of a generation rate of efflorescence in concrete by which the generation rate of efflorescence in concrete can be determined by objectively and quantitatively converting the rate into numeral values.SOLUTION: An evaluation method of a generation rate of efflorescence in concrete of the present invention includes the steps of: photographing images of a concrete test body before and after generation of efflorescence; calculating the average values of R (red), G (green), and B (blue) that are the three primary colors of light obtained from the respective image data, summing up the average values of R (red), G (green), and B (blue) to obtain the RGB total values; subtracting the RGB total value before the generation of efflorescence from the RGB total value after the generation of efflorescence to calculate the RGB change amount value; and evaluating a generation rate of efflorescence in concrete from the RGB change amount value, and a RGB change rate obtained from the RGB change amount value. |
