Durability (refer to Table 2-1, page 2-3).
Frost-resistant concrete
All other structures, w/c = 0.50
Weathertightness.
Freshwater exposure, w/c = 0.50
Select Lowest w/c Ratio
w/c = 0.46
Calculate Cement Content
Calculate Coarse-Aggregate (CA) Content
Refer to Table 2-6, page 2-14.
CA size = 3/4
FM of fine aggregate (FA) = 2.60 (given)
Determine volume of CA by interpolation of Table 2-6:
FM
2.40
2.60
2.80
Volume of CA (cf/cy)
17.8
17.3
16.7
(3/4-inch)
Weight of CA (G = volume from Table 2-6 x DRUW)
G = 17.3 x 104 lb/cfs = 1,799 1b/cy
Calculate FA Content by Absolute Volume Method
The absolute volume for any material can be described as for any material.
