Cement-Stabilized Subgrade (CSS) Soils

Cement Stabilized Subgrade Soils. CMS is a compacted mixture of pulverized in situ soil, water, and small proportions of cement that results in an unbound or slightly bound material. The treated material is similar to a soil but has reduced plasticity and a lower susceptibility to moisture, resulting in a more workable material.

Lime Vs Cement: Which Soil Stabilization Method is Better ...

Apr 23, 2021  Soil cement stabilization is a construction technique used to increase the strength of subgrade soil by mixing it with cement and water. The water hydrates the cement, generating reactions that create a matrix between the soil particles and gives the soil strength. Cement stabilization is especially useful in coarse-grained soils.
