The ideal ratio for a driveway is 0.50. You come by this number by dividing the amount of water you use in one cubic yard by the amount of cement in the mix (all in pounds). For example, if you have 470 pounds of cement, in order to get a ratio of 0.50, use the following formula: 470 x 0.50 = 235. So you would use 235 pounds of water in the ...
