Consolidation of Soil Equipment

Soil Consolidation Testing

Soil Consolidation Testing

When soil experiences a volumetric change in response to a change of pressure, it is known to undergo soil consolidation. Due to its makeup of both soil grains and pore fluid, soil is prone to capture excess water, increasing its pressure. This in turn affects the stiffness of soil, something crucial for any construction process. Also due to this, soil compaction is often tested both before and during important projects. more »

Soil Consolidation Testing, continued

Placing a load on a soil sample results in a reduction in the void space within the soil. In the laboratory, this load can be applied pneumatically or by simply placing weights on the sample. This process simulates the effects of real-world forces placed on soil whether from simple compaction or building structures on the soil. Incremental consolidation tests can be conducted by applying load increments to a soil sample for predetermined lengths of time. Generally, the load increments are determined by doubling the previous load.

The reason for performing incremental consolidation tests may vary; however, in most cases, the test is done to determine settlement properties of a particular soil. For example, when a building is constructed, the underlying soil is impacted by the load that has been applied and expels water from its voids. As water is expelled, the soil starts to settle, which affects the building above. In this scenario an engineer is interested in the magnitude and rate of settlement. In some cases, a building load may cause the soil to settle a number of feet. A consolidation test predicts the amount and rate of settlement.

Humboldt provides an extensive offering of consolidation testing equipment to satisfy the needs of any soils laboratory. From our fully-automated ConMatic IPC machine to our pneumatic or dead-weight consolidation testing machines, we have soil consolidation testing covered.

In addition, Humboldt carries an extensive offering of consolidation sample prep items, consolidation cells and components, as well as specific software to handle the specific testing process.
