Modelling the Pb release during Portland cement alteration [PDF]
Advances in Cement Research 21, 1 (2009) 1-10, 2014 Complex cementitious matrices undergo weathering with environmental exchange and can release metallic pollutants during alteration. The molecular mechanisms responsible for metal release are difficult to identify, though this is necessary if such processes are to be controlled.

Chemo-mechanical characterization of hydrated Calcium-Hydrosilicates with coupled Raman and nanoindentation measurements [PDF]
Applied Geochemistry Volume 118, July 2020, 104582, 2020 Celitement is a new type of cement that is based on hydraulic calcium-hydrosilicate (hCHS) that possesses a potential for minimizing the ratio C/S from above 3 in OPC down to 1, which significantly reduces the amount of CO$_2$ released during processing.
