Let ( B = M₂ - M₁ ) (SSD mass) Let ( C = M₃ - M₂ ) (mass of water added after aggregate) Let ( V_p ) = calibrated volume of pycnometer = mass of water to fill pycnometer (from calibration)
Bulk Specific Gravity (Dry): Based on the oven-dry weight of the aggregate. Let ( B = M₂ - M₁ )
| Parameter | Value | |-----------|-------| | Pycnometer volume (Vp) | 450.0 mL | | Mass empty pycnometer (M₁) | 200.0 g | | Mass pycnometer + SSD agg (M₂) | 700.0 g → SSD mass (B) = 500.0 g | | Mass pycnometer + SSD agg + water (M₃) | 985.0 g | | Mass of water added after agg (C = M₃ – M₂) | 285.0 g | | Mass oven-dry agg (M₄) | 490.7 g | Let ( B = M₂ - M₁ )
