Concrete Final Set Time Calculator
Extract actual penetration-resistance final setting threshold crossings at explicit verified method threshold, multiple witnesses/missing evidence retained, not predicted concrete placement window. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
Final concrete set uses an independently selected penetration-resistance criterion.
Final concrete set uses an independently selected penetration-resistance criterion.1
Interpolation of measured crossings does not determine later strength or establish a universal final-set threshold. Use Concrete Final Set Time Calculator to evaluate the supplied inputs under the model explained below.
When to use Concrete Final Set Time Calculator
Use Concrete Final Set Time Calculator to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Concrete Final Set Time Calculator and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Observed final set times hours, Observed final set penetration resistance mpa, Caller verified final set threshold mpa using the field table and validation rules below, then run the tool.
- Read Observed threshold witness hours, No observed threshold witness; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedFinalSetTimesHours | Observed final set times hours | array of number | Required; constraints below |
| observedFinalSetPenetrationResistanceMpa | Observed final set penetration resistance mpa | array of number | Required; constraints below |
| callerVerifiedFinalSetThresholdMpa | Caller verified final set threshold mpa | number | Required; constraints below |
Enter at least two strictly increasing nonnegative times in hours and aligned nonnegative penetration resistances in MPa, with a nonnegative caller final-set threshold. Return exact-threshold samples and linearly interpolated crossings in both directions. Plateau samples remain separate witnessed coordinates; no crossings means no observed threshold witness, not zero set time. No threshold, monotonicity assumption or loading approval is installed.
crossings = observed equality times plus interpolated strict sign changes; noWitness = crossings empty Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| observedThresholdWitnessHours | Observed threshold witness hours | array of number |
| noObservedThresholdWitness | No observed threshold witness | boolean |

}Limitations and assumptions
Interpolation of measured crossings does not determine later strength or establish a universal final-set threshold. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
