Software for the Estimation of Compression Index

The characteristics of the program CompIndex© are presented below.

The program is very easy to use, and will not expire (will work indefinitely -- except the demo version, of course).

It will work under all versions of Windows (but not DOS, UNIX, etc.).

Features of CompIndex©

Two dozen empirical correlations that can be used to estimate Cc from Liquid Limit (LL), Void ratio (e), water content (w), and various combinations of these indexes are employed.

See the main window


  • Cc from Liquid Limit, LL
  • Cc from Void Ratio, e
  • Cc from Water Content, w
  • Cc from LL, e, w combined
  • Various averages are also given
  • All data entry in one window
  • The statistics of the estimates are given

The results are presented graphically--see an example

Information about demos available today can be found at the demos web page of the EJGE website.
