1.We require a Portland cement concrete mixture for a small project on highway. The design mix will be quickly proportioned on the basis of weight with the ratio of cement:coarse aggregate: fine aggregate = 1:2:3. Cement content was specified at 5.90 bags per cubic yard (1 bag = 100 1b). The aggregates are SSD and have specific gravity of 2.65 for both aggregate types (coarse and fine). The specific gravity of the cement is 3.15. What is the water/cement ratio in terms of gallons per bags? (1 cubic foot = 7.48 gallons of water and 0% air content). (You must show the w/c with the stated units otherwise it will render 2 pts reduction. Show all your work for full credit. Report the final answer to the nearest 10th).
