Determine the quantities of materials required per cubic yard to create a concrete mix. The specifications state that the maximum aggregate size is 3 ½ " and require a minimum cement content of nine (9) sacks per cy and a maximum water-cement ratio of 0.60 with 9% air voids. Assume a 35%/65% fine/coarse aggregate ratio. Hint: use the average specific gravity for aggregate from your equation sheet to find the weight of aggregate.
(enter your answer to the nearest tenth (rounded). Do not use a percent sign or units.)
Volume of cement (cf/cy):
Volume of water (cf/cy):
Volume of air (cf/cy):
Volume of aggregate (cf/cy):
Volume of fine aggregate (cf/cy):
Volume of coarse aggregate (cf/cy):
Weight of coarse aggregate (lb/cy):
