Structure–Superstructure Inter-Relations in Ca2SiO4 Belite Phase

Autor: Vassilis Psycharis, Manolis Chatzigeorgiou, Dimitra Koumpouri, Margarita Beazi-Katsioti, Marios Katsiotis

Publikováno v: Crystals, Vol 12, Iss 12, p 1692 (2022)

Belite, the second most abundant mineralogical phase in Portland cement, presents five polymorphs which are formed at different temperatures. The increased interest in belite cement-based products is due to the lower environmental impact associated w

The Role of Titanium Dioxide on the Hydration of Portland Cement: A Combined NMR and Ultrasonic Study

Autor: George Diamantopoulos, Marios Katsiotis, Michael Fardis, Ioannis Karatasios, Saeed Alhassan, Marina Karagianni, George Papavassiliou, Jamal Hassan

Publikováno v: Molecules, Vol 25, Iss 22, p 5364 (2020)

Titanium dioxide (TiO2) is an excellent photocatalytic material that imparts biocidal, self-cleaning and smog-abating functionalities when added to cement-based materials. The presence of TiO2 influences the hydration process of cement and the develo

Segmentation of SEM images of multiphase materials: When Gaussian mixture models are accurate?

Autor: Manolis Chatzigeorgiou, Michalis Vrigkas, Margarita Beazi‐Katsioti, Marios Katsiotis, Nikos Boukos, Vassilios Constantoudis

Publikováno v: Journal of Microscopy. 289:58-70

Scanning electron microscopy has been a powerful technique to investigate the structural and chemical properties of multiphase materials on micro and nanoscale due to its high-resolution capabilities. One of the main outcomes of the SEM-based analysi
