PROBLEM TO BE SOLVED: To provide a blast treatment method that prevents the dispersion and diffusion of dust at low cost.SOLUTION: A blast treatment method comprises an abrasive forming step (S10) that fills a pore of porous material with water and then dries the surface of the porous material having a pore filled with water to form an abrasive, and an abrasive projection step (S12) that projects the abrasive onto a treatment object for collision with each other.SELECTED DRAWING: Figure 1 |
