This program
reduces and reports the data from one-dimensional consolidation or swell tests
(ASTM D2435 and D4546, Methods B and C). The software features full reduction
of time-consolidation data, including both square root and log of time
methods. Coefficient of primary and secondary consolidation, void ratios,
compression and recompression indices, preconsolidation and swell pressures,
T0, T50, T90 and T100, and
swell/collapse percentages are calculated and reported.
CONS is site licensed. One license fee covers unlimited installations at a single address and there are no ongoing maintenance costs.
Calculated Results
| Cc | Compression index |
| Pc | Preconsolidation pressure |
| OCR | Overconsolidation ratio |
| Cr | Recompression index |
| Cs | Swell index |
| E0 | Initial void ratio |
| EM | Void ratio at maximum past effective stress |
| EO | Void ratio at overburden pressure |

| γ | Unit weight (density) |
| MCi, MCf | Natural and post-test moisture content |
| Si, Sf | Initial and final saturation |

| Cv | Per-loading increment coefficient of consolidation |
| Cα | Coefficient of secondary consolidation |
New Features in Version 4
Multiple data acquisition files can be imported with a single action
Many data acquisition devices create a file for each loading increment performed. CONS version 1.x forced a time-consuming "Import file", "select append", "select file to import", "select loading pressure sequence" procedure for every loading increment. Version 4 allows an entire test's worth of loading increment files to be imported at once.
Reports can be exported in Adobe .PDF, .PNG and .EMF formats
You no longer need a third-party .PDF printer driver to create file copies of your swell/consolidation reports. The software can even create a .PDF report automatically and keep it update as you revise your data.
Compatibility with 64-bit Windows versions
The new version runs on both 32 and 64-bit versions of Windows 7, 8 and 10.
Loading increments are not confined to a single time-rate method
Both log10(time) and √time results can be reported for any given loading increment.
Easier construction line adjustment
Construction lines can now be dragged with the mouse.
What Hasn't Changed
You can still open any file created with earlier Windows CONS versions.
