Sustainable biopolymer soil stabilization in saline rich, arid conditions: a ‘micro to macro’ approach
Karen A. Thole,David Fawcett +1 more
TL;DR: In this paper , the effects of salinity (NaCl, 0-2.5 M) and temperatures associated with arid regions (25 °C, 40 °C) on Locust Bean Gum (LB) biopolymer stabilization of MT exemplar and sand (control) soil systems were investigated.
Journal ArticleDOI
Effect of Chitosan Solution on Low-Cohesive Soil’s Shear Modulus G Determined through Resonant Column and Torsional Shearing Tests
TL;DR: In this paper , the effect of using a biopolymer soil stabilizer on soil stiffness characteristics was investigated, and it was shown that chitosan solution added to medium-grained materials improved their shear strength, permeability or surface erosion.
Journal ArticleDOI
Mechanical and Microstructural Characterization of Rammed Earth Stabilized with Five Biopolymers
A. E. Losini,Anne Grillet,Monika Woloszyn,L. A. Lavrik,C. Moletti,Giovanni Dotelli,Marco Caruso +6 more
TL;DR: In this article , the compatibility of a selection of waste and recycled biopolymers for rammed earth applications in order to replace the more common cement-based stabilization was evaluated. But none of the materials were considered suitable as stabilizers.

Effects of Xanthan gum biopolymer on soil strengthening
TL;DR: In this paper, the effect of Xanthan gum on the performance of soil treatment in construction engineering has been investigated and it was shown that the effect depends on the type of soil, hydration level, and mixing method of the soil.
Journal ArticleDOI
Production, recovery and applications of xanthan gum by Xanthomonas campestris
TL;DR: Xanthomonas campestris is a water-soluble exo-polysaccharide and it is produced industrially from carbon sources by fermentation using the gram-negative bacterium Xanthomanias campstris as mentioned in this paper.
Journal ArticleDOI
Performance of compacted cement-stabilised soil
TL;DR: In this paper, the authors report on the Algerian experience on earth construction in housing and give an extended review of an experimental study to investigate a stabilised soil by either mechanical means such as compaction and vibration and/or chemical stabilisation by cement.
