ABSTRACT
In a cement-stabilized ground, the density of soil increases by consolidation. Simultaneously, stiffening of the soil occurs as a result of hydration. Previous tests using a mold-type consolidation apparatus have confirmed that an increase in unconfined compression strength occurs due to an increase in applied overburden pressure. In this study, a tank-type consolidation apparatus was developed by which both unimproved and improved parts were subjected to overburden pressure. The influence of the overburden pressure on unconfined compressive strength of cement-stabilized soil was examined. The tank-type consolidation apparatus showed similar tendency to those observed in the mold-type apparatus. Also, the strength of lower side of the soil column was found to be higher than that of the upper side. Moreover, the compressive strength of the specimen that was created using tank-type was lower than the straight line pattern of compression strength observed in a previous study using a mold-type.
