The lecture was held as a webinar on August 29, 2017
Our aim is the application of LIBS as a simple, quasi on-line method for the non-destructive testing of concrete. Concrete is naturally inhomogeneous. Therefore we must take into account the local variation of the element composition using a statistical analysis. Depending on how much cement and aggregate is measured with each laser pulse, a scan on the surface of a concrete specimen produces a distribution of points in the Rankin diagram which is used to characterise the concrete.
