Concrete Compressive Strength Calculation & ASTM Compliance
Automate lab quality assurance. Instantly convert cylinder and cube compressive strength tests, project 28-day cure trajectories from 7-day breaks, and calculate sub-base Lean Concrete volume.
Specimen Geometry Normalization
Converts cylinder ($150 \times 300$ mm) to cube ($150 \times 150$ mm) test loads with standard shape coefficient curves.
Cure Regression (3, 7, 14, 28 Days)
Predicts target 28-day design strength ($f'c$) from early break data to accelerate formwork stripping decisions.
Lean Concrete (LC) Sub-Base Sizing
Calculates theoretical volume requirements including compaction and subgrade variance tolerances.
Lab-Ready Output Formatting
Clean summarized output structured directly for compliance engineering field reports.
