Concrete Batch Admixture Calculator
Calculate product mass, active solids and solution water for a trial or production batch without converting the binder quantity separately.
Batch inputs
Use the approved basis
A dosage stated on product mass gives a different result from the same percentage stated on active solids. Confirm the current TDS or trial record.
Formula and limits
This is a mass-balance calculator. It does not choose a dosage or predict performance.
Binder = volume × binder content
Product-basis mass = binder × dosage ÷ 100
Active-basis product = active mass ÷ solids fraction
Product-basis mass = binder × dosage ÷ 100
Active-basis product = active mass ÷ solids fraction
- Binder includes the cementitious materials defined by the project mix.
- Solution water should be considered in effective-water accounting when required.
- Confirm meter resolution and batching tolerance before production use.
