Revolutionizing Concrete Analysis and Maintenance with Laser-Induced Breakdown Spectroscopy
Year: 2025
Type: article
Abstract: Laser-induced breakdown spectroscopy (LIBS) is a valuable complement to established methods for the chemical analysis of concrete. Compared to conventional techniques, LIBS enables spatially resolved imaging of harmful ion distributions within the cementitious matrix. It allows the simultaneous detection of all relevant ions and degradation mechanisms, facilitating a better understanding of interacting processes. The benefits of multi-element analysis are illustrated through selected examples that highlight the method’s superior information content. Ion penetration profiles are recorded at a resolution of 0.25 mm, providing high-quality input data for service life modelling. Instead of drill dust, a 50 mm core sample is used. The measurement is automated, requires no chemical reagents or elaborate sample preparation, and is completed within minutes.
