Design the concrete mix according to the following conditions.
Design Environment
Pavement slab, Bozeman, Montana (cold climate)
Required design strength=3000 psi
Slab thickness=12 in.
Statistical data indicate a standard deviation of compressive
strength of 250 psi is expected (more than 30 samples).
Only air entrainer is allowed.
Available Materials
Air entrainer: Manufacture specification is 0.15 fl oz/1% air/100
lb cement.
Coarse aggregate: 2 in. maximum size, crushed gravel (angular)
Bulk oven-dry specific gravity=2.573, Absorption=0.1%
Oven-dry rodded density=120 pcf
Moisture content=1%
Fine aggregate: Natural sand
Bulk oven-dry specific gravity=2.54, Absorption=0.2%
Moisture content=3.67%
Fineness modulus=2.68
