Influence of clay mineralogy on undrained shear strength using Fall cone test

Consistency limits are the basic parameters used as standard inputs for any soil investigation program to evaluate geotechnical properties of fine-grained soils. The primary objective this study is investigate variations in undrained shear strength clays with different plasticity based on fine content, clay mineralogy, and water absorption capacity. To achieve objective, 33 Fall cone tests were conducted low-, high-, very high-plastic mixtures. Various blends ensured by preparing mixtures Na-montmorillonite (NaM)/Ca-montmorillonite (CaM), (NaM)/Kaolinite (K), (NaM)/Sepiolite (S). According experimental results, highest liquid limit (LL) was obtained 100 % NaM at 255.07 %, whereas lowest LL S 33.55 %. Similarly, 160 kPa 30 content clay, 10 same content. Consequently, an framework, empirical equations which could be establish relationships among penetration-water limit-clay strength-cone penetration.
