Pozzolan Clinker Substitution Percent Calculator
Audit already mixed binder mass on explicitly separate total-binder versus pozzolan+clinker denominators, no recommended replacement or chemical efficacy. 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
A pozzolan share changes when the denominator includes other binder materials.
A pozzolan share changes when the denominator includes other binder materials.1
This calculator reports both the total-binder share and the pozzolan-plus-clinker share of an already mixed batch.
When to use Pozzolan Clinker Substitution Percent Calculator
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Prepare matched observations and independently established site, specimen, units, datum, and calibration context.
How to use Pozzolan Clinker Substitution Percent Calculator and understand its results
- Prepare matched observations and independently established site, specimen, units, datum, and calibration context.
- Enter observedAlreadyMixedPozzolanKg, observedAlreadyMixedClinkerKg, observedOtherBinderKg, following the field table and rules below, then run the tool.
- Read pozzolanPercentOfDeclaredBinder, pozzolanPercentOfPozzolanClinker. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedAlreadyMixedPozzolanKg | Observed already mixed pozzolan kg | list of number | Required |
| observedAlreadyMixedClinkerKg | Observed already mixed clinker kg | list of number | Required |
| observedOtherBinderKg | Observed other binder kg | list of number | Required |
Enter aligned nonempty nonnegative masses in kilograms. Sum each material inventory. The combined pozzolan and clinker mass must be positive. The first percentage includes other binder; the second excludes it.
p_total = 100P/(P+C+O); p_PC = 100P/(P+C) Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| pozzolanPercentOfDeclaredBinder | Pozzolan percent of declared binder | number |
| pozzolanPercentOfPozzolanClinker | Pozzolan percent of pozzolan clinker | number |

}Limitations and assumptions
Interpretation requires independently matched observations, units, site or specimen, and calibration. The calculation does not establish geological identity, operating safety, or an eruption forecast.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Evidence arrays must be dense, with no missing cells. Numeric observation lists allow at most 10,000 entries, subject to any smaller bounds stated above.
Alternative or Complementary methods
For a related review, use Volcanic Ash Cement Replacement Safe Checker: Volcanic ash used in a binder requires evidence from tests matched to the relevant material and method. This tool records how supplied test observations compare with independently established acceptance bands; its result does not approve a replacement mix. For a complementary step, use Perlite Expansion Ratio Industrial Lookup: Perlite expansion is a ratio between matched expanded and original volumes. Pooling those volumes gives a result weighted by original volume, which can differ from the simple average of specimen ratios.
