The importance of physical, chemical, and mineralogical properties in selecting soils stabilized by activated natural pozzolan (ANP) was demonstrated. Five soil banks were identified, and two were selected: B1Z due to its SiO2 content and the presence of Montmorillonite and B3M for its granulometry and plasticity. Electrical con- ductivity (EC) was measured to monitor reactivity by testing two stabilizers, ANP and lime. Soils with 2.5% ANP exhibited higher EC than those with 10% lime. Compressive strength (CS) was analyzed. Soils with 10% ANP recorded higher CS than those with lime. Chemical and mineralogical properties were more relevant than physical ones in selecting soils stabilized through ANP.
