Compressed earth blocks can be stabilized or not. Additives for stabilization are cement or lime.
The input of soil stabilization allows for higher buildings with thinner walls, which have a much better compressive strength and water resistance. Cement stabilization is better for sandy soils. Lime stabilization is better suited for clayey soils. The selection of a stabilizer will depend upon the soil quality and the project requirements.
Cement will be preferable for sandy soils and to achieve quickly a higher strength. Lime will be rather used for very clayey soil, but will take a longer time to harden and to give strong blocks.
