SURFACE TREATMENT OF CONCRETE

摘要

A method of treating a surface for the removal of a surface portion by scabbling comprising the steps of oscillating, in a first direction, a laser beam incident upon the surface and superimposing a nett direction of travel of the incident laser beam over the surface in a second direction such that the incident laser radiation traverses the surface so as to effect surface removal. The amplitude of oscillation of the laser beam incident upon the surface may be less than a width of the incident laser beam. The method avoids areas adjacent to a scabbled area being effected so as to no longer be amenable to scabbling and provides a more even scabbled surface.
