Curing Allow the stabilized soil to cure and gain strength The curing process involves keeping the stabilized layer moist by watering or covering it with geotextiles to prevent excessive drying Adequate curing time is essential for the stabilized soil to form stable bonds resulting in a strong and durable stabilized soil layer

Crushed clay stabilized layer

Lime stabilized clay and Portland cement stabilized sand are two examples The chemical stabilizers normally added at a 2 to 10% rate increase soil internal cohesion via chemical bonding Chemically stabilized soils which are stiffer and stronger than the unreinforced soils also exhibit tensile cracking as a major mode of failure

Strength and Microstructure of Cement Stabilized Clay

The adsorption of Ca 2 ions onto the clay particle surface decreases the repulsion between successive diffused double layers and increases edge to face contacts between successive clay sheets Thus clay particles flocculate into larger clusters which increases in the plastic limit with an insignificant change in the liquid limit vide Table 1
