Aeolian sand serves as the principal foundation material for construction in desert regions, yet its stabilization predominantly relies on cement, presenting critical carbon emission challenges. This study developed a cementitious utilizing complementary industrial solid wastes (ISWs)—steel slag (SS), ground granulated blast-furnace (GGBFS), phosphorus (PS), and carbide (CS)—based clinker three chemical moduli (TCM) simplex lattice design, aiming to replace cement aeolian stabilization. ISW dosage effects stabilized strength mechanical properties were investigated, with mechanisms studied via phase microstructural analysis. Results demonstrated that GGBFS exerted most significant positive influence of sand. The optimal proportion was determined SS:GGBFS:PS:CS = 5:35:20:40, achieving comparable cement-stabilized literature. elastic modulus ductility exhibited linear exponential negative correlation uniaxial compressive strength. hydration products ISWs, including C(-A)-S-H gel ettringite similar clinker, effectively enhanced interparticle bonding pore-filling capacity. proportions governed composition distribution products, thereby modulating density strength, ultimately dictating macroscopic performance variations. conclusions provide an environmentally friendly solution regions.
