5. Determine the batch quantities for a concrete mix design (Non-air entraining) that is to have a 28-day compressive strength of 2500 psi, using angular coarse aggregates from a No.4 sieve opening to 1 in . size, and a medium fine aggregate with a fineness modulus of 2.65. A slump of 6 in . is desirable.
Assume the specific gravity of cement is 3.14 and one sack weights 94 lbs . Also assume that the unit weight of water \(=62.4\mathrm{lb}/\mathrm{ft}^{3}\). Use the design Tables 5.4 and 5.5 as shown in the textbook. The following descriptions apply to the coarse and fine aggregates:
Coarse Aggregates:
Sieve No.4 to 1 in., Angular
Absorption (\%)=0.1
Specific Gravity (bulk dry)\(=2.7\)
Specific Gravity (bulk saturated surface dry)\(=2.74\)
Dry-rodded unit weight \(\left(\mathrm{lb}/\mathrm{ft}^{3}\right)=101.5\)
Fine Aggregate:
Fineness modulus \(=2.65\)
Absorption (\%)\(=0.8\)
Specific Gravity (bulk dry)\(=2.4\)
Specific Gravity (saturated surface dry)\(=2.45\)
