Question: Determine the batch quantities for a concrete mix design that is to have a 2 8 - day compressive strength of 2 5 0 0

Determine the batch quantities for a concrete mix design that is to have a 28-day compressive strength of 2500 psi using rounded
aggregate from a No.4 sieve opening to 1 in. in size and a medium-fine aggregate with a fineness modulus of 2.65. A slump of 3 in.
is desirable. The following descriptions apply to the coarse and fine aggregates.
Coarse Aggregate
Size, No.4 to 1 in., rounded
Absorption (%)=0.1
SG (bulk dry)=2.7
SG (bulk saturated surface dry)=2.74
Dry-rodded unit weight (lb/ft3)=101.5
Fine Aggregate
Fineness modulus =2.65
Absorption (%)=0.8
SG (bulk dry)=2.4
SG (bulk saturated surface dry)=2.45
