Constant Rate of Strain (CRS) Cell

The Constant Rate of Strain (CRS) test provides an efficient and a rapid method to determine properties (stress history, compressibility, hydraulic conductivity, and rate of consolidation) of a cohesive soil and possess many advantages over the incremental oedometer test. Labor Saving, Better definition of the compression curve, Quicker Test than conventional Incremental loading (IL).

The strain rate is selected and monitored to produce a base excess pressure ratio according to ASTM D4186 by the HM-5475 or HM-5480 loading frames.
