Cement Suspension Flow through Heterogeneous Porous Media
Cement permeation grouting is a soil improvement method applied to increase the strength of a soil body and/or lower its hydraulic conductivity. This method is particularly useful in cases where surface access is limited and where soil disturbance cannot be tolerated, for example when improving soil below an existing structure. Cement permeation grouting has been extensively studied and our understanding of the mechanisms controlling its successful application has improved remarkably over the past decades. However, most of the performed studies consider homogeneous porous media, and understanding the effect of soil heterogeneity on grout propagation is still lacking. In fact, soil heterogeneity is often considered a limitation when trying to apply lab test results to field applications. This paper introduces a 2D grouting setup to research grouting of heterogeneous layered soils. The paper presents preliminary test results demonstrating the effect of soil heterogeneity on grout flow compared to flow in homogenous soils.
