    • Preliminary Study on the Mechanical Activation and High‐Temperature Treatment of Saponite‐Containing Tailings Generated during Kimberlite Ore Dressing 

      Drozdyuk, Tatiana; Frolova, Maria; Ayzenshtadt, Arkady; Calay, Rajnish K; Jhatial, Ashfaque Ahmed (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-13)
      This study investigates transformations of a pre-mechanically activated saponite-containing material with subsequent high-temperature treatment. The thermogravimetric analysis confirmed that the mechanical activation of saponite leads to the destruction of its layered structure, accompanied by the release of silicon dioxide and magnesium oxide in free form. The values of surface activity for ...

    • A Review on Emerging Cementitious Materials, Reactivity Evaluation and Treatment Methods 

      Jhatial, Ashfaque Ahmed; Novakova, Iveta; Gjerløw, Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-05)
      Alternative to traditional concrete, sustainable concrete reduces cement content, waste management issues, and CO2 emissions. To achieve sustainable concrete, waste materials can be used as supplementary cementitious materials (SCMs) to partially replace cement. Fly ash, ground-granulated blast furnace slag, and silica fume have been heavily studied as SCMs. However, due to the retirement of coal-fired ...
