This study presents a new improvement mechanism of nano-SiO2 treated loess and assesses its effects on the soil environment. The results show that the nano-SiO2 additive produces a larger and more uniform aggregate structure in the treated loess accompanying a novel homogenization process. It results in increases in unconfined compressive strength and Young's modulus. Meanwhile, the addition of small quantities of nano-SiO2 also strikingly increases the mechanical properties. As a whole, nano-SiO2 has potential for use as a cost-effective and environment-friendly stabilized additive.
