| Abstract: |
| A new type of soil strengthened agent sourced mainly from industrial wastes was presented. The physical parameters of its strengthened soils, including unconfined compression strength, coefficient of permeability, compressive modulus, cohesion, angle of internal friction and the strength of static load test were compared with those of cement soil. Moreover, two expressions of anticipating the unconfined compression strength of the strengthened soils were presented, and the strengthening mechanism of the new agent was discussed. |
