“…The bonded consolidation layer acts as a "sand crust" with a certain shear strength on the surface of the moving sand, isolating the underlying loose sand grains from near-surface wind-blown sand. Compressive strength and thickness are key indicators of the mechanical properties of the consolidation layer (Meng et al, 2013;Liu et al, 2012). Our study finds that with an increase in the amount of sand stabilizer used, the consolidation layer becomes thicker, and the compressive strength increases (Figure 5).…”

To explore the sand stabilization effects of the Robinia pseudoacacia sand stabilizer, a series of spraying experiments was conducted using different dry matter dosages (0.5, 1, 2, 3, 4, and 5 g/m2). The sand stabilization effects, mechanical properties, and wind erosion conditions of the stabilizer were measured. The results show the following: 1) after spraying the sand stabilizer, a consolidated layer with a thickness of 1–14 mm is formed on the sand surface. The average compressive strength increased by 206.21% compared to the control group (0 g/m2), and wind erosion was reduced by 35.47%–65.92%. 2) The compressive strength of the consolidation layer positively correlated with the dosage and thickness (the depth or the vertical dimension of the consolidation layer) (p < 0.05) and inversely correlated with wind erosion and total porosity. As the dosage increased, the total porosity decreased, the thickness of the consolidation layer increased, and the compressive strength increased even more, making the material more resistant to wind erosion.

“…The polymerised materials, as the new sand-fixing materials to control sand wind erosion, have received much attention [28]. They mainly included polyacrylamide, polyvinyl alcohol, vinyl acetate-ethylene copolymer emulsion and polyurethane and so on [29][30][31][32][33][34]. After the polymerised materials had been sprayed on the sand surface or mixed with sand, they showed their cementing ability to aggregate sand particles and form crusts on the sand surface.…”

For the first time, the salt-resistant emulsion was applied as an ecological sand-fixing material to enhance the sand-fixing ability in salty desert. This study started from the synthesis of the novel salt-resistant poly(vinyl acetate-dibutyl maleate-acyclic acid-sodium p-styrene sulphonate) copolymer emulsion. Then, the structure, composition and thermal property of the emulsion were characterised. The sand-fixing properties and ecological effect of the emulsion were evaluated. The experimental results showed that the emulsion has been successful synthesised and could be used as an ecological sand-fixing material. The related reason is that, first, the emulsion could significantly visibly enhance the sand-fixing ability in high saltaffected sand land. Second, the prepared emulsion had good thermal aging resistance and freeze-thaw stabilities to withstand the changes in the temperature of salty desert, and the test of the influence of the emulsion on the growth of microbe of sand showed a favourable ecological effect.

“…Therefore, CSS is very potential to combine with VSS to form an comprehensive ecological sand-stabilising method. 21 Synthetic polymer materials, [22][23][24] for CSS have shown higher efficiency and lower pollution, compared to traditional sand-stabilising materials like cement, 25 peat, 17,26 clay, 27 sodium silicate 28 and petroleum products. 29 Among these polymeric materials, polyurethane (PU) is one with outstanding properties but insufficient study.…”

Chemical sand stabilisation (CSS) shows potential to collaborate with vegetation for desert restoration. Among the materials used in CSS, polyurethane (PU) is one of excellent properties but restricted by the limited forms used for CSS. This paper presents an anionic waterborne PU dispersion (PUD), a dispersion form of PU, for CSS. Its composition, particle size distribution (PSD) and zeta potential were characterised by Fourier transform infrared spectroscopy and laser particle size analyser. Results of its performance in CSS showed the stabilisation distinctly improved sand in anti-wind erosion and water-retaining properties by forming a consolidated crust on sand surface, with no harm to seed germination. The changes of stabilised sand showed strong dependence on the material concentration, which was discussed based on the visual inspection, SEM and EDS results.
