Soil Stabilization - The Effects of Mixing Conditions, Method of Compaction, and Curing Conditions on the Effective Stress-Strength Behavior of a Stabilized Soil

摘要

The effects of mixing conditions, method of compaction, and curing conditions on the strength behavior of a cement-stabilized clayey silt were investigated using consolidated-undrained triaxial compression tests with pore pressure measurements. The results were analyzed using the Mohr-Coulomb criterion of failure in terms of effective stresses. The results of the testing program showed that the consistency of the soil prior to the addition of cement is the most important factor controlling the mixing quality. The use of a mechanical device for mixing was not found to be inherently inferior to the standard laboratory mixing procedure. (Author)
