The soil material in soil-cement can be almost any combination of sand, silt, clay, gravel, or crushed stone. Local granular materials, such as slag, caliche, limerock, and scoria, plus a wide variety of waste materials including cinders, fly ash, foundry sands, and screenings from quarries and gravel pits, can all be utilized as soil material. Old granular-base roads, with or without bituminous surfaces, can also be reclaimed to make great soil-cement. Soil-cement is sometimes called cement-stabilized base, or cement-treated aggregate base. Regardless of the name, the principles governing its composition and construction are the same. But it is not suitable for all types of soil such as organic soil, acid soil, sulfate soil and uniform sand.The soil becomes stabilized because the cement reacts chemically with the soil particles and bind them together. But these above soil containing component prevent the chemical reaction.
