The aggregate specific gravity used in calculations must be consistent with the moisture condition assumed in the basic aggregate batch weights -- i.e., i.e., b bulk ulk dry dry if aggregate weights are stated on a dry basis, and bulk SSD if weights are stated on a saturated-surface-dry basis. saturated-surface-dry

For the method of determining the amount by which average strength should exceed design strength, see ACI 214.
Aggregate absorption of 0.5 percent is disregarded since its magnitude is unconsequential in relocation to other approximations.
