Cement Stabilization of Embankment Materials

Cement Stabilization of Embankment Materials Abstract Embankment subgrade soils in Iowa are generally rated as fair to poor as construction materials. These soils can exhibit low bearing strength, high volumetric instability, and freeze/thaw or wet/dry durability problems. Cement stabilization offers opportunities to improve these soils conditions.

Soil stabilization with cement and affect the cement ...

Soil stabilization with cement. The process of cement stabilization can be done by mixing the portland cement and pulverized soil with water and compacting the mix to attain a strong material. The material takes place y mixing soil and cement is known as soil-cement. The material becomes hard and durable structural material as the cement hydrates and develops strength.
