Effect of different ions on dissolution rates of silica and feldspars at high pH
Karen Scrivener, Barbara Lothenbach, Mahsa Bagheri, Mahdieh Shakoorioskooie
The dissolution kinetics of silica-containing minerals in aggregates influences strongly the process of ASR in concrete. In this paper, the effect of different ions on the dissolution rates of SiO2 (amorphous and quartz) and feldspars at high pH values was ...
PERGAMON-ELSEVIER SCIENCE LTD2022Aggregate dissolution in different pore solutions
The occurrence of cracking due to alkali silica reaction (ASR) affects the service life of concrete structures. The dissolution of silica-containing minerals within aggregates causes the formation of ASR products, which fill macroscopic cracks and cause th ...
EPFL2021Role of Iron Sulfide Phases in the Stability of Noncrystalline Tetravalent Uranium in Sediments
Rizlan Bernier-Latmani, Luca Loreggian
Uranium (U) in situ bioremediation has been investigated as a cost-effective strategy to tackle U contamination in the subsurface. While uraninite was believed to be the only product of bioreduction, numerous studies have revealed that noncrystalline U(IV) ...
AMER CHEMICAL SOC2020Dissimilarities in polyphosphate accumulation between Shewanella loihica and the model bacterium Shewanella oneidensis
Polyphosphate plays an important role in the physiological adaptation of bacteria during growth and development, as well as in their response to nutritional and environmental stresses. Moreover, polyphosphate accumulation is of environmental relevance and ...
