Special Issue Information

Dear Colleagues,

We are pleased to announce the launch of a Special Issue on “Artificial Geomaterials: Applications of 3D Printing and Other State-of-the-Art Technologies”, which is now open for submissions.

Geomaterials are materials inspired by geological systems originating from the billion years long history of the earth. The safety and reliability of subsurface engineering activities and geotechnical infrastructures built on/in/by geomaterials will be increased if a comprehensive understanding of their behavior under certain boundary conditions is achieved through systematic experimental investigations. Application of natural rocks for these investigations sometimes leads to uncertain results due to their strong heterogeneity in terms of composition and pre-existing microstructures. Therefore, in those cases, artificial geomaterials are inevitably preferred. Moreover, preparation of the specimens/models with complex geometries using natural rocks and conventional materials such as gypsum plaster and concrete through traditional techniques is either impossible or extremely time- and cost-consuming. Today, 3D printing technology and other state-of-the-art techniques are available as promising alternatives to make artificial geomaterials. These cutting-edge techniques have a great potential to be implemented in rock mechanics, rock engineering, mining engineering, engineering geology, petroleum engineering, and subsurface gas storage studies, especially during the specimen preparation stage. The capability of rapid and consistent manufacturing of complicated models with high geometrical accuracy is the most enticing feature of these techniques.

This Special Issue aims to highlight the applicability and application of advanced technologies and approaches to prepare artificial geomaterials. Prospective authors are invited to submit their original contributions in the form of research articles, review articles, or short communications within the scope of this Special Issue. Topics of interest for this Special Issue include but are not limited to the following:

  • Artificial geomaterials;
  • 3D-printed geomaterials;
  • Hydro-mechanical properties of artificial geomaterials;
  • Applicability and application of 3D printing technology to geomechanics;
  • Application of advanced technologies to make artificial geomaterials;
  • Applications and limitations of conventional artificial geomaterials;
  • Limitations of applying natural rocks for experimental studies;
  • Physical modeling using artificial geomaterials.

The geomechanical and transport properties of rocks are of great importance to geoscience and engineering, as these properties provide responses to external stresses and flow regimes in the subsurface. Typically, experiments conducted on cores from reservoir formations have a degree of uncertainty, due to the heterogeneous characteristics of rock samples. To combat this uncertainty, binder-jet additive manufacturing (3D printing) is an emerging technology to characterize natural porous media in a repeatable fashion. In this study, the 3D printing sandstone analogue involved sand powder and organic binder to mimic silica grains and cement in natural sandstone. The use of compaction rollers and the adjustment of printing parameters allowed one to test how the porosity and strength of 3D-printed samples can replicate the transport and geomechanical properties of natural sandstone. The densities of samples were increased by ~15% and compressive strength by ~65% with the use of the larger roller. This is a promising alternative to experimental testing to calibrate numerical models in geoscience and engineering. The significance of this approach is to allow for customizable porosity, permeability, and strength in rock samples, while preserving scarce natural rock samples. Full article
