Influence of sodium-based activators and water content on the fresh and hardened properties of metakaolin geopolymers

Autor: Isabel Pol Segura, Peter Arendt Jensen, Anne Juul Damø, Navid Ranjbar, Lars Skaarup Jensen, Mariana Canut

Publikováno v: SN Applied Sciences, Vol 4, Iss 10, Pp 1-16 (2022)

Article highlights An elevated water content can improve the fluidity of the pastes, however, it increases pore formation and detriments the strength. A surplus of alkali content decreases the fluidity, accelerates the setting, and increases the shri

A review: Alkali-activated cement and concrete production technologies available in the industry

Autor: Isabel Pol Segura, Navid Ranjbar, Anne Juul Damø, Lars Skaarup Jensen, Mariana Canut, Peter Arendt Jensen

Publikováno v: Heliyon, Vol 9, Iss 5, Pp e15718- (2023)

A growing interest in alternative cements has emerged with the sole purpose of reducing the environmental footprint associated with cement production. One of the promising alternatives is to use non-carbonate materials such as alkali-activated materi

Autor: Qisheng Wu, Anne Juul Damø, Shaopeng Li, Zhang Jianbo, Xinguo Xi, Xinjuan Hou, Huiquan Li, Hao Wu, Pengpeng Hu

Publikováno v: Hu, P, Hou, X, Zhang, J, Li, S, Wu, H, Damø, A J, Li, H, Wu, Q & Xi, X 2018, ' Distribution and occurrence of lithium in high-alumina-coal fly ash ', International Journal of Coal Geology, vol. 189, pp. 27-34 . https://doi.org/10.1016/j.coal.2018.02.011

High-alumina-coal fly ash (HAFA) with a high Li content is regarded as a potential resource for Li production. To support the development of Li recovery technology from HAFA, the distribution and modes of occurrence of Li in HAFA were investigated. H

Electron microscope investigations of activated chalcopyrite particles via the FLSmidth® ROL process

Autor: Anne Juul Damø, Adam Paul Karcz, Sara Rocks, Chaiko David J, Kim Dam-Johansen, Jytte Boll Illerup

Publikováno v: Karcz, A P, Damø, A J, Illerup, J B, Rocks, S, Dam-Johansen, K & Chaiko, D 2017, ' Electron microscope investigations of activated chalcopyrite particles via the FLSmidth® ROL process ', Journal of Materials Science, vol. 52, no. 20, pp. 12044-12053 . https://doi.org/10.1007/s10853-017-1308-y

Because of its unique semiconductor properties, the world’s most abundant copper mineral, chalcopyrite (CuFeS2), is refractory with respect to atmospheric leaching using traditional acidic ferric sulfate lixiviants. FLSmidth® has developed a novel

Publikováno v: Lv, C, Wu, H, Lin, W, Illerup, J B, Karcz, A P, Ye, S & Damø, A J 2019, ' Characterization of elemental sulfur in chalcopyrite leach residues using simultaneous thermal analysis ', Hydrometallurgy, vol. 188, pp. 22-30 . https://doi.org/10.1016/j.hydromet.2019.05.020

A key component in the atmospheric leaching of metal sulfides is the oxidation of sulfide to either elemental sulfur or hexavalent sulfur. The final oxidation state of sulfur significantly influences the economic viability of a leaching process becau
