Why the application needs its own trial plan
Structure an OPC grinding-aid trial around equivalent fineness, sulfate balance, throughput, energy and strength.
A result is comparable only when product quality and operating boundary are defined before the trial.
Baseline data checklist
- Clinker mineralogy and gypsum source
- SO₃ target and sulfate balance
- Baseline fineness and residue
- Mill circuit and stable production rate
- 1/3/7/28-day strength
- Setting time and water demand
Recommended trial sequence
- Stabilize and record an untreated baseline.
- Confirm product identity, density and dosing calibration.
- Apply one agreed dosage step without changing unrelated controls.
- Wait for circuit stabilization and collect time-matched process and cement samples.
- Compare process, cement quality and economics together.
