Abstract

This study investigates the effects of sodium hydroxide activated steel slag on the mechanical properties of loess. The results show that the addition of sodium hydroxide reduced the optimal moisture content, significantly increased the unconfined compressive strength and water stability of loess in the early stages, and effectively improved its shear strength in the later stages. Among these, sodium hydroxide had the most significant impact on the mechanical properties and water stability of the loess after 28 days. This study provides scientific evidence and technical reference for the application of chemically activated steel slag in loess subgrade improvement.
