Santos Silva, A.; Cruz, T.; Paiva, M.J.; Candeias, A.; Adriano, P.; Schiavon, N.; Mirão, J.P.Abstract Historical mortars from sixteenth to seventeenth century military forts located at the mouth of the Tagus River in Lisbon have been characterized by polarized light microscopy (PLM), thermal analysis (TG/DTA), X-ray diffractometry (XRD) and scanning electron microscopy + energy dispersive spectroscopy (SEM + EDS). The results indicate that the mortars used were all hydraulic lime-based. The presence o...
Abandoned mine slags analysis by EPMA WDS x-ray mapping
Guimarães, Fernanda; Rosado, L.; Morais, C.; Candeias, A. E.; Pinto, A. P.; Mirão, J.
