The technique of improve soft soils with vacuum consolidation, is a technique that is more and more used, in different places of the world, because it offer a series of advantages in relation with others techniques of improve soft soils, depending of the kind of project. The laboratory tests are important fonts of information for projects of improve soft soils. This work isan experimental study for use vacuum in laboratory, for consolidation tests with one-dimensional load (conventional, in the Bishop s press) and with isotropic load (in the triaxial cell), using remolded material. For make this,was fundamental the development of procedure for the execution of eachtests. Various difficulties happened during this development, this situationforced to test different techniques until to obtain a satisfactory operation.With the development of the procedures was done a series of tests forknow the results, that these tests provide. With the results obtained weredone analyses for its interpretation.
