Abstract

Despite competing with several established conventional techniques, deep-section laser concrete cutting is foreseen to find a niche market in contaminated environments, such as in the decommissioning of nuclear power plants, where effective waste management is of critical importance. In a BNFL-sponsored development project at UMIST it has recently been shown that deep cuts of up to 500 mm - a new world record for concrete cutting depth - can be obtained fairly easily. A 1.2 kW CO2 laser and a 1.5 kW high-power diode laser were used in the investigation. In this paper details of the technique are discussed, along with typical problems that have to be overcome. Aspects of cutting reinforcing steel bars in the concrete matrix are also briefly discussed.
