Learn how soil-cement stabilisation helps transform weak soil into a stronger foundation for construction.
How Does Soil-Cement Stabilisation Work?
- Soil preparation: The existing soil is pulverised and prepared.
- Cement mixing: A suitable quantity of cement is mixed uniformly with the soil.
- Water addition: Water is added to achieve the required moisture condition.
- Compaction: The mixture is compacted to the specified density.
- Curing: The treated soil is cured to allow cement hydration and strength development.
Applications of Soil-Cement Stabilisation
- Road subgrade and pavement base construction
- Improving the strength of suitable weak soils
- Embankments and selected earthwork projects
- Reducing soil plasticity and improving durability
The effectiveness of soil-cement stabilisation depends on soil type, cement content, moisture, compaction and curing conditions. Laboratory testing is essential to determine a suitable mix.
Conclusion
Soil-cement stabilisation is an important ground improvement technique that can make suitable weak soils stronger and more durable for construction applications.
