Design Environment Pavement slab,

Fineness modulus = 2.47

Design the concrete mix according to the following conditions.

Design Environment Pavement slab, Bozeman, Montana (cold climate) Required design Slab thickness = 12 in. strength = 3000 psi

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 Absorption = 0.1%gravity = 2.573,

Oven-dry rodded density = 120 pcf

Moisture content = 1%

Fine aggregate: Natural sand

Bulk oven-dry specific Absorption = 0.2%gravity = 2.54,

Moisture content = 3.67%

Fineness modulus = 2.68
