Overview

Randomized trial demonstrates improved soil stability in oil-contaminated clay using cement and rice husk ash blend, suggesting effective remediation.

Key Points

  • The research aims to enhance the strength and stability of oil-contaminated clay soils using a blend of cement and rice husk ash.
  • Investigated the effects of different ratios of Portland Limestone Cement and Rice Husk Ash on soil properties.
  • Measured undrained shear strength and bearing capacity after treatment.
  • Evaluated cost-effectiveness for foundation applications.
  • Optimal strength achieved at 8% PLC with 4% RHA, undrained shear strength improved from 32.24 to 140.77 kN/m².
  • Bearing capacity increased from 67.40 to 244.86 kN/m² with the optimal blend.
  • Settlement was reduced from 117 mm to 11 mm using 8% PLC with 2% RHA.
