Lime Applications in Soil Stabilization
RCI’s quicklime and hydrated lime are suited for soil stabilization in construction and infrastructure projects, providing an effective solution for improving soil strength and workability. Lime reacts with fine-grained soils, such as clay and silt, through a process known as cation exchange and pozzolanic reactions. This transforms unstable, moisture-laden soils into a dry, firm, and load-bearing material.
The initial reaction involves lime reducing soil moisture through hydration, which immediately improves workability. Over time, pozzolanic reactions occur as lime reacts with the silica and alumina in the soil, forming stable calcium silicate hydrates (CSH) and calcium aluminate hydrates (CAH). These compounds enhance the soil’s compressive strength and durability.
Lime stabilization is particularly effective for high-plasticity clay soils and other fine- grained materials with poor bearing capacity. It is commonly used in road construction, foundations, and embankments, offering a cost-effective and sustainable solution for challenging soil conditions.
