This program reduces and reports the data from one-dimensional consolidation or swell tests (ASTM D2435 and D4546, Methods A and B). 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.
