Improvement Of Sandy Soil Properties By Using Bentonite

The main goal of this study is studying the improvement engineering properties soil mass. These are shear strength and maximum dry density which effect on foundations structures their stability. cohesionless can be given some cohesion by rearrangement particles decrease voids between adding fine them increase density, then required improved. chemical combinations due to additives also generate new bonded materials give mass a good properties. In study, different percentages Bentonite were added soil. grain size distribution sample classification was (sandy poorly graded) according Unified Soil Classification. compaction test made for (2.5, 5, 7.5, 10)% Bentonite. direct same parameters (C & Ø) changed. Adding 7.5% graded sandy gives better results than other used in present study.
