Consolidometer Tests on Fresh Cement Grout
The report proposes that the consolidation of cement grouts takes place by the laying down of a very stiff grout cake through the removal of excess water. The grout cake has a water/cement ratio of approximately 0.44 by weight, and a permeability of about .56 x 10(-6) m/s. The subsequent behavior is apparently similar to that of a reconstituted clay soil, with a very high stiffness during unloading and reloading at stress levels less than the pre-consolidation. The behavior for load increases above the preconsolidation pressure could not be analyzed using Terzaghi's model of primary consolidation without inferring permeabilities considerably lower than were found in the first phase.
