Abstract: Because of its vast deposits and slow rate of resource utilization, phosphogypsum (PG), a by-product of the production of phosphate fertilizer, has emerged as a pressing environmental issue. In this study, sodium silicate was blended into PG road stabilizers to change their properties, and the curing method was examined. The ideal mixture was identified by optimizing the ratios of PG, cement (C), silica fume (SF), and slaked lime (SL) using the extreme vertex mixing scheme. Based on this, various ratios of sodium silicate were externally doped, and the changed materials’ strength characteristics, water resistance, and hazardous ion curing impact were all methodically examined.According to the study, doping the PG-cured materials with sodium silicate could greatly increase their strength and water resistance while also successfully enhancing their structural densification and lowering the leaching of harmful ions. These findings showed promising application potential.
