Soil Cement Topic - American Concrete Institute

Soil cement is a densely compacted mixture of portland cement, soil/aggregate, other cementitious materials (possibly), and water. It is used primarily as a base material for pavements, but also for slope protection, low permeability liners, foundation stabilization, and other applications.

The Use of Soil Cement as a Highway Material

Since the first controlled soil-cement construction was carried out near Johnsonville, South Carolina in 1935 (2), soil-cement has been considered a valuable engineering material. It is now an accepted practice to denote the result of adding cement to soil as a soil-cement mixture (3), or in other words, soil-cement is the stabili­

The additive can be either portland cement, lime or salt (sodium chloride). For stabilizing soils with cement, nearly all soil types can be used, from gravelly and sandy to fine-grained silts and clays. Generally, the more granular materials are used because they pulverize and mix readily and require the least amount of cement.
