Astm C128 Specific Gravity And Absorption Of Fine Aggregate Pdf ^hot^ [TRUSTED]
For G~2.62, SSD mass 500 g → displaced water = 500/2.62 = 191 mL. If pycnometer volume = 450 mL, then water added C = 450 – 191 = 259 mL. Then Bulk SSD = 500/(450-259) = 500/191 = 2.62 ✅.
[ G_sa = \fracM₄V_p - C - (B - M₄) ] Where ( B - M₄ ) = water absorbed. For G~2
Then: [ G_sb(SSD) = \fracBV_p - C ]
[ G_sb(SSD) = \frac\textSSD mass\textSSD mass - (\textmass pycnometer + water to mark - mass pycnometer + SSD agg + water) ] Actually, simplified: For G~2
