    • Bleeding and sedimentation of cement paste measured by hydrostatic pressure and Turbiscan 

      Peng, Ya; Lauten, Rolf A; Jacobsen, Stefan; Reknes, Kåre (Journal article; Peer reviewed, 2016)
      Sedimentation and bleeding of cement pastes with lignosulfonate were studied by visual observation, HYdroStatic Pressure Test (HYSPT) and Turbiscan measurements showing two bleeding stages: a fast initial phase followed ...

    • Effect of materials on sedimentation of cement paste 

      Peng, Ya; Jacobsen, Stefan (Chapter; Peer reviewed, 2013)
      A conceptual model for the stability of paste was proposed and an experimental system, HYdroStatic Pressure Test (HYSPT), was developed for detecting the sedimentation of fresh cement paste. By accurate measurements of the ...

    • Filler and Water Reducer Effects on Sedimentation, Bleeding and Zeta-Potential of Cement Paste 

      Peng, Ya; Pedersen, Bård; Ng, Serina; De Weerdt, Klaartje; Jacobsen, Stefan (Journal article; Peer reviewed, 2018)
      Bleeding and sedimentation quantify the stability of fresh cement paste, whereas the addition of fillers and water reducers affect the stability. The effect of various types of fillers and water reducers was investigated ...

    • Sedimentation and Bleeding of Cement Paste 

      Peng, Ya (Doktoravhandlinger ved NTNU, 1503-8181; 2014:89, Doctoral thesis, 2014)
      The lower viscosity and high matrix volume of Self-Compacting Concrete (SCC) compared to ordinary concrete can lead to instability in the form of particle segregation, sedimentation and bleeding. This is a problem for the ...
