- Laser scabbling has the potential to systematically remove the surface layer of concrete, and can therefore help in safely and economically decommissioning nuclear structures. Most researchers associate the scabbing effect with thermal spalling, which depends on free water. This study uses a range of novel experimental measurements, including infrared thermography, to accurately characterise the scabbling process and to investigate parametrically the impact of moisture and concrete constituents on the success of laser scabbling. It concludes that cement decomposition processes, rather than free water, are the key scabbing parameters. This knowledge can help design more reliable and economic decommissioning technologies.
