DOI: 10.1007/s10064-018-1361-z

Abstract: Protracted degradation of the loess structure during technogenesis leads to changes in the microaggregate composition, density, and moisture. We have developed a model that predicts the value of the porosity coefficient of loess in a… read more here.

DOI: 10.1007/s13762-020-02974-9

Abstract: Bio-cementation is currently appraised to solidify sandy soils, but only few studies use it to cement loess soil particles. The effects of the addition of loess soils on bacterial growth, urease activity, and productive rates… read more here.

DOI: 10.1016/j.catena.2018.10.006

Abstract: Abstract A series of laboratory tests were conducted on intact specimens of two loess soils to characterize their collapsibility, shear strength, microstructure and mineralogy. In addition, microstructural observations were performed on the specimens after various… read more here.

DOI: 10.1038/s41598-024-83258-x

Abstract: Collapsible loess soils, known for their significant volume reduction upon the wetting, pose critical challenges in the geotechnical engineering. The estimation of the wetting-induced settlement is crucial for the foundation design and the determination of… read more here.

DOI: 10.1080/19386362.2021.1981650

Abstract: ABSTRACT Vast land areas in northeastern Iran are covered with loess soils being susceptible to collapse and excessive settlement after moistening. Different improvement techniques were developed for loess soils, including compaction, immersion, or reinforcement. However,… read more here.
