Method And Apparatus For Cutting Concrete By Use Of Laser

The slag formed when concrete is melted by exposure to a laser beam, when caused to incorporate therein a MgO-rich supplementary material, loses it viscosity and, on cooling, refrains from expanding and, consequently, assumes a readily removable state. The slag thus set can be easily removed by allowing a cleaning device such as the rotary wire brush to pass along the part of concrete melted ...
