Expansion Index Consolidometer is used to determine the swelling potential of compacted soils through moisture conditioning a soil specimen to 50 percent saturation and compacting the sample into a 4x1in (101.6x25.4mm), IDxH stainless steel specimen ring. The confining load is applied, and the specimen is immersed in water for up to 24 hours as the volumetric swell is recorded. From this, the Expansion Index (EI) of the soil is determined, with a higher EI indicating an expansive soil.
This self-contained unit can mount, load, and saturate the soil sample; a separate consolidometer loading device is not required. The unit is stainless steel, with a corrosion-resistant anodized aluminum base and collar. The HM-562 includes a stainless-steel specimen ring, 12.6lb (5.7kg) loading weight, and two porous stones.
The MA-333 Mechanical Dial Indicator – 0.5 x 0.0001in or MA-363 Digital Dial Indicator – 0.6 x 0.0001in are required for testing with this unit and sold separately. Additional porous stones, stainless steel specimen rings, and loading weights are available separately for more efficient sample preparation.

Included Items:
- Expansion Index Consolidometer
- (2) Porous Stones
- Stainless Steel Specimen Ring
- Loading Weight
- Dial Indicator Bracket
Accessories:
- MA-333 Mechanical Dial Indicator – 0.5 x 0.00001in (Range x Divisions) measures the volumetric swell of the sample used to calculate the EI; the mechanical or digital dial indicator is required for use
- MA-363 Digital Dial Indicator – 0.6 x 0.0001in (Range x Resolution) measures the swell of the soil sample and is a digital alternative to traditional mechanical dial indicators; the digital or mechanical dial indicator is required for use
- GSA-332 Porous Stone is 3.995in (101.5mm) in diameter, 0.5in (12.7mm) thick, and supports both ends of the sample, allowing for the flow of fluid through the soil specimen
- HMA-775 4in Filter Paper Grade 55 for use with Porous Stones to prevent pore blockage from soil fines
- HMA-665 Stainless Steel Specimen Ring for compacting soil specimens to be tested
- HMA-667 Loading Weight used to produce confining load before the specimen is saturated
