Shotcrete Accelerator Dose Calculator
Audit already added shotcrete accelerator/cement binder mass ledger with verified active content, not chemical dose prescription, strength efficacy or material safety. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
An accelerator ledger distinguishes the product added from its active component.
An accelerator ledger distinguishes the product added from its active component.1
Comparing either with cement-binder mass describes the recorded mixture rather than prescribing a dose.
When to use Shotcrete Accelerator Dose Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
How to use Shotcrete Accelerator Dose Calculator and understand its results
- Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
- Enter observedAlreadyAddedAcceleratorKg, observedMatchedCementBinderKg, callerVerifiedAcceleratorActiveFractions, using the field meanings and rules below, then run the tool.
- Read observedProductAcceleratorBinderFraction, observedActiveAcceleratorBinderFraction. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedAlreadyAddedAcceleratorKg | Observed already added accelerator kg | list of number | Required |
| observedMatchedCementBinderKg | Observed matched cement binder kg | list of number | Required |
| callerVerifiedAcceleratorActiveFractions | Caller verified accelerator active fractions | list of number | Required |
Use aligned already-added accelerator kilograms≥0, binder kilograms>0 and active fractions [0,1]. Divide total product mass by total binder and total product×activeFraction by total binder. Return dimensionless fractions.
productFraction=Σproduct/Σbinder; activeFraction=Σ(product×active)/Σbinder Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedProductAcceleratorBinderFraction | Observed product accelerator binder fraction; dimensionless fraction, not a percent | number |
| observedActiveAcceleratorBinderFraction | Observed active accelerator binder fraction; dimensionless fraction, not a percent | number |

}Limitations and assumptions
Units, ledger boundaries, survey interpretation and model applicability must be independently established. These summaries do not assign reserve/resource classifications or establish support adequacy, ventilation safety or an operating setting.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
Alternative or Complementary methods
For a related step, use Shotcrete Rebound Percentage Calculator: Rebound fraction needs collected rebound and delivered shotcrete on the same dry-mass basis. For a complementary comparison, use Solid Liquid Ratio Calculator: Solid-to-liquid volume ratio differs from mass ratio when component densities differ.
