Expansion Index Consolidometer/Expansion(Swell) Test Equipment

Standard : ASTM D4829

Description

SL204 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 4x1 in (102x25mm) stainless steel specimen ring.

The confining load is applied and the specimen is immersed in water for up to 24 hours as 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 is capable of mounting, loading, and saturating the soil sample; a separate consolidometer loading device is not required.

The unit is constructed of stainless steel, with an corrosion resistant anodized aluminum base and collar.

The SL204 includes a stainless-steel specimen ring, 12.6lb (5.7g) loading weight, and two porous stones.

Either the Mechanical Dial Indicator – 0.5 x 0.0001in or Digital Dial Indicator – 0.6 x 0.0001in are required for testing with this unit and sold separately.

Included Items:

• Expansion Index Consolidometer
  
• Two Porous Stones
  
• Stainless Steel Specimen Ring
  
• Loading Weight
  
• Dial Indicator Bracket
