Immobilization of (Aqueous) Cations in Low pH M-S-H Cement

Autor: Maximilian R. Marsiske, Christian Debus, Fulvio Di Lorenzo, Ellina Bernard, Sergey V. Churakov, Cristina Ruiz-Agudo

Publikováno v: Applied Sciences, Vol 11, Iss 7, p 2968 (2021)

Incorporation of heavy metal ions in cement hydrates is of great interest for the storage and immobilization of toxic, hazardous, and radioactive wastes using cementitious matrix. Magnesium silicate hydrate (M-S-H) is a low pH alternative cementitiou
