The expansion index consolidometer performs the Expansion Index Test which predicts the swelling potential of compacted soils. The self-contained design does not require a separate consolidation loading device for testing.
After compaction, the sample goes into the consolidometer with a porous stone at each end and loaded with the stainless steel weight. Consolidation goes on for 10 minutes at which point the assembly submerges into water to initiate the test. The loading weight and top porous stone equal a weight of 12.6 pounds which generates a total pressure of 1 lbf/in2 on the sample.
The consolidometer’s immersed parts feature stainless steel and anodized aluminum construction for durability and corrosion resistance. A 5102 dial indicator – 0.5″ range x 0.0001″ divisions or 6820 digital dial indicator – 0.6″ range x 0.0001″ resolution are required for the test.
Includes:
- Anodized aluminum base and collar with stainless steel hold-down rods
- Dial indicator bracket
- Stainless steel specimen ring
- Loading weight
- Porous stones
