Cement-Modified Soils (CMS)

A cement-modified soil (CMS) is a soil material that has been treated with a relatively small proportion of portland cement – less cement than is required to produce hardened soil-cement. The objective of the treatment is to amend undesirable properties of problem soils or substandard materials so that they are suitable for use in construction.
