Zou, L., Håkansson, U. and Cvetkovic, V. (2019). Cement grout propagation in 2D fracture networks: impact of rheology. Proceedings in Earth and Geosciences: Rock Mechanics for Natural Resources and Infrastructure Development, CRC Press, 2019, Vol. 6, s. 2486-2493.

Cement grouts propagation into a two-dimensional water-saturated fracture networks with different values of rheological properties are simulated by using an extended two-phase flow model. The cement grouts are typical non-Newtonian fluids that contain yield stress, which are often assumed as Bingham fluids. The aim of this study is to investigate the impact of Bingham rheological properties, i.e. yield stress and plastic viscosity, on cement gouts propagation in two-dimensional fracture networks.
