Geologic repositories for radioactive waste are designed as multi-barrier disposal systems that perform a number of functions including the long-term isolation and containment of …
Thermodynamic modelling can reliably predict hydrated cement phase assemblages and chemical compositions, including their interactions with prevailing service environments …
MgO contained in cementitious materials is experimentally observed to precipitate as poorly crystalline hydrotalcite (Mg-Al LDH). However, the geochemical modelling of hydrotalcite is …
This article summarizes long-term degradation mechanisms of cementitious materials in contact with fresh and saline solutions based on a review of experimental observations in …
In this study, the structure of synthetic magnesium silicate hydrated phases (MSH) and the distribution of water as a function of the Mg/Si ratio were investigated. Different analytical …

The addition of MgCl 2 to synthetic calcium silicate hydrate (CSH) with Ca/Si= 0.8 lowers the pH values below 10. Experimental observations and thermodynamic calculations show the …
Calcium silicate hydrate (CSH) and magnesium silicate hydrate (MSH) have been described as two separate phases. This work investigates their stability domains and the possible …
The incorporation of aluminum in magnesium silicate hydrate (MSH) phases was investigated. Magnesium (alumino) silicate hydrate (M-(A-) SH) with Mg/Si ratios equal to 1.1 …
Abstract “Low-pH” cementitious materials have been developed in the context of nuclear wastes encapsulation to reduce the alkaline plume and the early hydration heat causing …
