edxia: Microstructure characterisation from quantified SEM-EDS hypermaps

The characterisation of cement paste microstructure is an important step towards understanding durability mechanisms in cementitious materials. Scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS) a widely used technique to analyse the at micron-scale. However, it challenging, notably because characteristic size many phases found on scale smaller than EDS interaction volume. This work presents new image analysis framework identify and quantify materials from SEM-EDS hypermaps. By leveraging domain knowledge, representative points are attributed mixtures based ratio plots. Then, quantitative can be carried out (chemical composition, particle distributions, volume fractions, …). We demonstrate abilities framework, we present possible applications extensions method. available as both graphical interface Python code.
