The crystal-chemical properties of clinker relicts within different types of aged cementitious materials were defined, integrating standard microstructural analysis by scanning electron microscopy with quantitative microchemical and micromineralogical analyses by electron microprobe and electron backscatter diffraction. The peculiar mineralogical, chemical and textural features observed raise interesting questions concerning the long-term hydration kinetics of clinker phases in operating conditions.

A neutron diffraction study of the nuclear and magnetic structure of goethite (-FeOOH) with varying crystallinity and temperature is presented. The antiferromagnetic structure in the Pb′nm color space group suggests spins aligned parallel to the c axis. A significant reduction in the Néel temperature was found for a nanocrystalline sample.
