5. Enter the ages (F) at which you want the predicted compressive strength based on the measured
energy
6. Read the predicted compressive strength in the "Estimated Compressive Strength" fields (G)
Optional advanced use:
For verification and fine-tuning of predicted Compressive Strength values, you can perform physical
strength testing as an "adjustment data point" on a sample at any curing age and enter the
corresponding result in the "Correction: Age" and "Correction: Strength" fields (H). I-Cal Strength will
adjust all predicted compressive strength values proportionally. In the example below, physical
strength testing was done at 36 hours. This data point is plotted as a square on the graph, and the
overall CS(t) curve adjusted accordingly.
