What is Soil Cement?

Soil-cement is a simple, high-compacted mixture of soil, Portland cement, and water. As the cement reacts, or hydrates, the mixture gains strength and improves the engineering properties of the raw soil. It improved strength and durability, combined with its low first cost and ease of construction, make soil-cement an outstanding value for use as a base and subbase material.

The major variables that control the properties and characteristics of soil-cement mixtures are the type of soil or aggregate material , the proportion of cement in the mix, the moisture conditions, and the degree of compaction. It is possible, simply by varying the cement content, to produce soil-cement that ranges from a basic modification of the compacted soil (termed cement-modified soil) to fully-hardened soil-cement that is strong, durable , and frost resistant.
