Plastic concrete for cut-off walls: A review

Abstract

The remediation of earthen dams is of growing interest worldwide. Plastic Concrete cut-off walls hereby provide an effective method to control dam seepage. However, Plastic Concrete material behaviour is not yet thoroughly understood. The review presented here confirms that Plastic Concrete may be consiered to be a low-strength, low-stiffness impervious concrete with high deformation capacity under load, but also supports the need for further investigations into the mechanical and hydraulic material properties. This review provides an important opportunity to advance in the understanding of the material behaviour of Plastic Concrete and make a contribution towards a more realistic design of Plastic Concrete cut-off walls.
