CONCRETE SURFACE PROCESSING METHOD AND LASER-PROCESSED CONCRETE SURFACE
PROBLEM TO BE SOLVED: To provide a surface processing method for concrete in which vitrifying is suppressed even when high-speed processing is performed.SOLUTION: In a surface processing method of concrete, a surface of the concrete is irradiated with a laser beam so that a beam spot is scanned along a predetermined scanning pattern and the scanning pattern moves along the surface at a predetermined feed speed. When the beam spot repeatedly passes through a predetermined portion in the scanning pattern, an overlap ratio, which is a ratio of overlapping of a passage path of the beam spot over a passage path of the beam spot in an immediately preceding irradiation, is 90% or less.
