Influence of lead, zinc, iron (III) and chromium (III) oxides on the setting time and strength development of Portland cement
TLDR
In this article, a fractional factorial design (24−1) of experiments was carried out to study the influence of metal oxides on cement properties: unconfined compressive strength (UCS), setting time (ST), bulk density (BD) and noncombined water (NCW).About:

Recycling MSWI bottom and fly ash as raw materials for Portland cement
TL;DR: The results indicate that cement production can be a feasible alternative for MSWI ash management and it is also evident that the addition of either fly ash or bottom ash did not have any effect on the compressive strength of the clinker.

Photocatalytic activity of semiconductor-modified cement. Influence of semiconductor type and cement ageing
TL;DR: In this article, the photocatalytic atrazine degradation by white Portland cement samples modified with different semiconducting oxides (TiO 2 in form of Degussa P25, Hombikat UV 100, coarse-grained anatase, and ZnO) was used as a model reaction to investigate a possible application of modified cements for the degradation of pollutants on building surfaces.

Arsenic Waste Management: A Critical Review of Testing and Disposal of Arsenic-Bearing Solid Wastes Generated during Arsenic Removal from Drinking Water
TL;DR: Current disposal options for arsenic-bearing wastes, including landfilling, stabilization, cow dung mixing, passive aeration, pond disposal, and soil disposal are summarized and compared to results from shorter, regulatory tests.

A review of solidification/stabilization interferences
S. Trussell,R.D. Spence +1 more
TL;DR: In this paper, the authors present a review of the literature on interferences between hazardous wastes and cement and the fundamental chemical mechanisms by which the inhibition of cement set takes place and reach some conclusions about the potential effects of most waste constituents even in the absence of particular studies on specific compounds.
Journal ArticleDOI
Leaching effects on silicate polymerization. An FTIR and silicon-29 NMR study of lead and zinc in portland cement
TL;DR: In this paper, the lead and zinc nitrate-doped Portland cement samples were investigated by 29 Si solid-state NMR and Fourier transform infrared spectroscopy and the results indicated that silicate polymerization is slightly enhanced with lead doping and retarded in the presence of zinc.

Influence de la composition d'un ciment portland sur son hydration en presence de zinc
G. Arliguie,J. Grandet +1 more
TL;DR: In this article, the influence of other constituent of Portland cement is investigated and it is shown that free calcium in Portland Cement is a favorable element as well as an important proportion of C3A and minor elements have no influence on the conversion reaction of zinc hydroxide.
