C147 Large Coarse-grained soils Consolidation Instrument
C147 Coarse Grain Large Consolidation Apparatus CGJ
This test is to determine the relationship between deformation and pressure (or porosity and pressure) of coarse-grained soil, and the relationship between deformation and time in order to calculate the compression coefficient, compression index, rebound index, volume compression coefficient, compression modulus, and consolidation of soil Coefficient and preconsolidation pressure. Suitable for coarse-grained soil with a maximum particle size of 60mm.
The instrument consists of a consolidation container, a loading device, a displacement meter, etc. The consolidation pressure, consolidation time and consolidation rate can be adjusted.
The loading pressure corresponding to the sample area corresponds to a constant axial force, and the deformation of the consolidation coefficient is measured.software interface
