PROBLEM TO BE SOLVED: To directly perform quality control of building materials during and after the use, by qualitatively and quantitatively grasping the types and origins of used materials.SOLUTION: The method of identifying a bulk material in an article includes adding, to a bulk material, a pigment-containing polymer dispersion in which particles are coded with pigment mixtures, and quantitatively measuring polymer dispersion particles. The bulk material includes liquid and solid bulk materials. The liquid bulk material includes a concrete fluidization agent and a grinding aid, and the solid bulk material includes concrete, cement, and clinker.SELECTED DRAWING: None |
