TL;DR: In this paper, the laser-induced breakdown spectroscopy (LIBS) was used to measure the chloride content of reinforced concrete cores and the results were compared with the results of standard chemical methods.

TL;DR: In this paper, the applicability of pulse phase thermography (PPT) for the investigation of structures is studied systematically on concrete test specimens and on a plastered sandstone column.

TL;DR: In this paper, a dual-arm Echelle-Raman spectrograph is integrated into a single system for molecular and elemental microanalyses, where both Raman and laser-induced breakdown spectroscopy are performed on the same ~ 0.002mm 2 sample spot allowing the assessment of sample heterogeneity on a micrometric scale.

TL;DR: In this article, laser-induced breakdown spectroscopy has been employed for the investigation of the sulfur content of concrete, and the optimum ambient atmosphere has been determined by comparison of measurements accomplished under air, argon and helium atmosphere.

TL;DR: In this paper, different CCD-detectors were compared with respect to high quantum efficiency and high dynamic range, which is necessary for simultaneous detection of weak spectral lines from trace elements and intense spectral lines of main elements.
