DOI: 10.1016/j.jrmge.2021.01.010
Abstract: Abstract It is difficult to collect and characterise well-preserved samples of weakly-cemented granular rocks as conventional sampling techniques often result in destruction of the cementation. An alternative approach is to prepare synthetic geomaterials to match… read more here.
