TLDR
In this article, it is shown that the physicochemical properties of the matrix are time dependent and that the intrinsic performance of blended cement matrices improves with maturation, and that matrix interactions with waste species are characterised using chromium, molybdenum, uranium and arsenic as examples.About:

Immobilisation of heavy metal in cement-based solidification/stabilisation: a review.
TL;DR: It is concluded that further research on the phase development during cement hydration in the presence of heavy metals and thermodynamic modelling is needed to improve effectiveness of cement-based s/s and extend this waste management technique.
Journal ArticleDOI
Materials and processes for the effective capture and immobilization of radioiodine: A review
TL;DR: In this paper, the authors provide a comprehensive summary of the current issues surrounding processing and containment of 129I, the isotope of greatest concern due to its long half-life of 1.6 × 107y and potential incorporation into the human body.
Journal ArticleDOI
Leaching mechanisms of oxyanionic metalloid and metal species in alkaline solid wastes: A review
TL;DR: In this article, an overview is presented on possible mechanisms that control the leaching behavior of oxyanion forming elements in cementituous systems and alkaline solid wastes, such as municipal solid waste incinerator bottom ash, fly ash, and air pollution control residues, coal fly ash and metallurgical slags.
Journal ArticleDOI
Treatment and use of air pollution control residues from MSW incineration: An overview
TL;DR: This work reviews strategies for the management of municipal solid waste incineration (MSWI) residues, particularly solid particles collected from flue gases, focusing upon management strategies used in various countries, waste composition, treatment processes and possible applications.
Journal ArticleDOI
Geopolymers for immobilization of Cr6+, Cd2+, and Pb2+
TL;DR: The results of this work tentatively support a previous identification of Pb (3)SiO(5) as a potential candidate phase for hosting Pb(II) within the geopolymer structure, although the data are not entirely conclusive.

Selective dissolution of hydrated blast furnace slag cements
K. Luke,Fredrik P. Glasser +1 more
TL;DR: In this paper, the content of blast furnace slag (BFS) in blended cements composed of BFS and OPC was investigated and a variety of dissolution procedures were investigated.
Journal ArticleDOI
Cement hydrate phase: Solubility at 25°C
TL;DR: In this paper, the solubility data for some of the principal cement hydrates are given for low and medium level radioactive waste repositories in the U.K. This in turn will be used to predict nuclide immobilisation/migration in the near field environment.
Journal ArticleDOI
Compositional Model for Calcium Silicate Hydrate (C-S-H) Gels, Their Solubilities, and Free Energies of Formation
TL;DR: In this article, a compositional model based on available structural evidence is proposed for amorphous calcium silicate hydrogel, which is applicable to gels in the (Ca/Si),solid range 1.0 to 1.4 and is formulated to take account of dimeric silicate species in the solid.
Journal ArticleDOI
Solubility and Aging of Calcium Silicate Hydrates in Alkaline Solutions at 25°C
TL;DR: In this article, an analysis of aqueous phases in equilibrium with 85 C-S-H gels is presented, showing that the concentrations fit smooth curves over the range of increasing sodium concentrations, where anomalous data correspond to solids with low lime contents.
