The total cement mass in the batch.
Air-entraining admixture dosage is calculated per unit of cement, not total concrete volume.
The admixture's dosage rate from its manufacturer data sheet.
This varies significantly by product and target air content — always use the specific rate from your admixture's technical data sheet, not a generic assumption.
Admixture volume needed
0.0395 gal
The dosage rate you entered directly determines the result — always confirm it against your specific admixture's manufacturer data sheet, since rates vary widely between products and target air-content levels.

How this was calculated
Formula source(s)
- Admixture dosage is expressed per unit cement mass on the manufacturer's technical data sheet — total admixture volume = (total cement mass / 100 kg) x dosage rate per 100 kg of cement
Inputs used
- Total Cement Mass in Batch
- 1100 lb
- Dosage Rate (mL per 100 kg cement)
- 30
Intermediate steps
- Equivalent in mL
- 149.69 mL
Confidence note: The dosage rate you entered directly determines the result — always confirm it against your specific admixture's manufacturer data sheet, since rates vary widely between products and target air-content levels.
What this calculation does not cover
- This converts a dosage rate you supply into a volume. It does not predict the air content the batch will actually reach, which depends on cement alkali content, fly ash carbon, sand fines, slump, water content, mix temperature, mixing time and haul time, none of which are inputs here. Confirm the target with a field air test (ASTM C231 or C173) on the load you are placing.
- The dose is taken against cement mass alone. Most manufacturers publish their rate per 100 kg of total cementitious material, and fly ash, silica fume and slag change how much admixture a mix needs, with high-carbon fly ash in particular demanding substantially more. Check which mass basis your data sheet uses before entering a figure.
- The dosage-rate box always means millilitres per 100 kg of cement, including with the site switched to imperial. It is the one field on this page with no unit switch, so a North American data sheet quoting fluid ounces per 100 lb of cement has to be converted by hand before you type it in.
- Nothing here accounts for air lost between the batch plant and the finished surface. Pumping, especially through a boom downline, plus over-vibration, extended haul time and over-finishing all strip entrained air. The volume returned is a batching quantity, not the air that ends up in the hardened concrete.
- This is not a mix design or a durability check. It does not test the resulting dose against the air content your exposure class requires, does not account for interaction with water reducers, superplasticisers or retarders batched alongside it, and does not verify the hardened air-void system.
