Test Level
Critical for freeze-thaw durability
🧸
STEP 1 / 1
Air Content Test
Measure total air void content in fresh concrete
🧸
Enter Air Content Parameters
Enter initial and final pressure readings to calculate total air content.
📝 Standards
  • ASTM C231: Standard Test Method for Air Content of Freshly Mixed Concrete by the Pressure Method
  • ASTM C173: Standard Test Method for Air Content of Freshly Mixed Concrete by the Volumetric Method
  • Pressure method: air = (1 - reading/type A reading) x calibration factor x 100%
  • Typical air content for non-air-entrained: 1-3%; air-entrained: 4-8%
  • Correction for coarse aggregate: subtract V_agg / V_total from reading
