Abstract
A method and apparatus for cutting thick sections of cement-based materials, the method comprising mutually traversing a surface to be cut with a laser beam at a power density sufficient to produce a depth of molten material having a maximum depth of 10 mm at each traverse; allowing the molten material to solidify; breaking the solidified material into particles; and removing the particles by suction means.

A method for cutting thick sections of cement-based materials, the method comprising:
- mutually traversing a surface to be cut with a laser beam at a power density sufficient to produce a depth of molten material having a maximum depth of 10 mm at each traverse;
- allowing said molten material to solidify;
- breaking said solidified material into particles;
- and
- removing said particles by suction means.
An apparatus for cutting thick sections of cement-based materials in which material is made molten and allowed to solidify, the apparatus comprising
- a means for mutually traversing a surface to be cut with an unfocused laser beam at a power density sufficient to produce a depth of molten material having a maximum depth of 10 mm at each traverse;
- a means for breaking the solidified material into particles;
- and
- a suction means for removing the particles.
