A Laboratory Study on Shear Behavior of Biocemented Chlef Sandy Soil
https://orcid.org/http://orcid.org/0000-0003-0170-1418
Sand reinforced with hydraulic binder (cement) has played an important role in recent decades. However, the natural properties of soil have deteriorated due to pollution resulting from excessive use of cement. Today, the use of biopolymers as a soil improvement method has become very popular. However, since biopolymers are organic and degradable, their long-term effects are not fully understood.
This study investigates the effectiveness of using xanthan gum as a binding agent to improve the shear strength and volume change behavior of Chlef sandy soil. Samples were prepared with varying xanthan gum percentages (XG = 0.25%, 0.5%, and 1%) and curing times (7, 14, and 30 days) at a medium relative density (Dr = 50%). The samples were subjected to normal stresses of 50 kPa, 100 kPa, and 200 kPa.
Results showed significant improvement in the shear strength, cohesive intercept, and friction angle of the treated sand. The study highlights the potential of using xanthan gum as a microbiological binding agent and provides insights for the long-term effectiveness of sand reinforcement.
