cement-stabilized soil, and cement-stabilized aggre- gate base are sometimes used. Cement-modified soil can be a hardened, unhardened or semihardened mixture of soil and cement. When relatively small quantities of portland cement and moisture are added to a soil material, the chemical and physical properties of that soil material are improved.
