The Effect of Moisture Content at Compaction and Grain Size Distribution on the Shear Strength of Unsaturated Soils

The soil moisture content at shearing and other factors, including dry density grain size, influence its shear strength. This study investigated the effect of compaction size distribution on unsaturated Triaxial compression tests were performed in laboratory using modified triaxial apparatus silica sands No. 3 6 without fines with 20% to explore strength characteristics. Test samples compacted sheared various combinations soil’s optimum residual content. analysis test results shows that showed higher peak when Further, show fines, content, finding this endorses considering for geotechnical design structures while predicting
