【 摘 要 】

Laser ablation is being studied as a method both for removing and for measuring contaminated surface layers from concrete. The objectives of this research are to determine the mechanism and efficacy of laser ablation, to understand the chemistry of contaminated concrete surfaces, and to chemically and physically characterize the captured ablation effluent, which would become the stored waste. The method is attractive because it adds no additional waste, offers fine control over the amount of material removed, can work on cracked, curved or irregular surfaces, and can potentially be instrumented for real-time contamination analysis. While the focus of this project is on concrete, the technology should be applicable to any surface requiring contaminant removal.
