Feasibility study on artificial preparation of structured loess

Abstract Structure collapse and subsidence are non-negligible geotechnical problems in loess areas. Within this framework, homogeneous undisturbed samples critical for effective research on structure. Hence, a novel method preparing artificial structured (ASL) was proposed. The calcium oxide (CaO) added to air-dried natural (NL) form carbonate (CaCO 3 ) cementation the ASL with various densities were successfully prepared. Further, microstructure test, shear collapsibility test conducted NL feasibility analysis. Results show that compared NL, enough CaCO could also be generated among particles; presented similar compositional structural characteristics higher strength. of affected by its density: would not occur when density exceeded certain threshold.
