a Cube samples obtained by consolidating different aggregates with 20 wt.% PUAO-50. b Compressive strength and elastic modulus of the consolidated samples. c A large desert sand-based consolidated sample (30 cm × 20 cm × 4 cm) withstanding repeated rolling of a 2-ton car. d Compressive strength, elastic modulus, and morphology change of desert sand-based consolidated samples during continuous UV irradiation for 1000 h. e Engineering structures built by mechanically machining and assembling plate, column, and beam samples made of desert sand-based consolidated samples. f Directly formed complex-shaped desert sand-based consolidated samples. g Process of PUAO-50 consolidating standard sand underwater. h Underwater sand consolidated sample could support a 20-kg kettle bell without dispersion. The centre of error bars and the error bars respectively correspond to the mean value and standard deviation of 3–6 measurements for each analysis.
