Expansion Index Test Apparatus
• Completely self-contained and compact design.
• Accurate to 0.0001” (0.002 mm).
• Testing time of 24 hours or less on cured soil specimens.
The Expansion Index Test Apparatus is a completely self-contained apparatus designed for use in determining the expansion index of soils. Using the new consolidation apparatus, contractors and laboratory technicians can conduct an expansion test on a cured soil specimen in 24 hours or less.
The apparatus is designed to control all of the variables that influence the expansive characteristics of a particular soil while still performing a practical test for general engineering use.
