MECHANISMS OF STABILIZATION - The National Academies Press

Portland cement is comprised of calcium-silicates and calcium-aluminates that hydrate to form cementitious products. Cement hydration is relatively fast and causes immediate strength gain in stabilized layers (3). Therefore, a mellowing period is not typically allowed between mixing of the components (soil, cement, and water) and compaction.


Following the initial mixing, lightly compact the material to seal it against rain or excessive drying by using a steel wheel or pneumatic tire roller. Before final mixing, cure the initially-mixed, lightly-compacted material for a period of not less than 24 hours and not more than 7 days. Perform the initial cure with water.

Construction Specification 29—Soil Cement

Portland cement shall conform to the requirements of Material Specification 531, Portland Cement, for the speci-fied type. Mixing of different brands or types of cement is not permitted. Portland cement shall be furnished in bags, barrels, or bulk. Bagged cement that is stored at the job site shall be


Cement is spread on the soil material in front of the mixing machine. Cement spreading should be completed in the first working lane and under way in the second lane before mixing operations are begun. This ensures a fullwidth cement spread without a gap between lanes and keeps spreading equipment out of the way of mixing equipment.

How to Use and Install Soil-Cement

Soil-cement is a mixture of Portland cement, natural soil, and water used to form a hard, semi-rigid paving surface.It is most often used in highways or as a sub-base for asphalt or other forms of paving, but it can also be used as a cheap stand-alone paving surface for driveways, sidewalks, patios, or garage floors.
