TRI-X 150-200(Triaxial Cell 150 MPa 200°C)

General Features 

    Ground test relies on the idea first that behavior of the mass of the ground can be, with necessary conditions, predicted in the way that some peculiar qualities can be determined. Tests of the ground, well conducted, constitute a sure base of 

knowledge to permit theirs exploitations with the best conditions. This cell has 

been realized to determine bearing capacity of the ground and its land 

subsistence when this one is under triaxial strength, by executing measures linked by the product saturation contained. This enable the specimen, under test, to submit pressure conditions simulating the ones existing in the mass of the ground. The rock sample properties are determined by laboratory test.
