fairfaced concrete mix design

Fairfaced Concrete Mix Design

bre concrete mix design method,a desired level of workability is chosen. the ratio of sand to coarse aggregate is chosen to produce a satisfactory plastic concrete. generally there is a minimum amount of sand necessary to fill the voids between the course aggregate particles. increasing the percentage of sand makes for a less harsh and more easily placed mix..actual concrete mix ratios for 3000, 3500, 4000, and 4500,the concrete ticket below shows a 3500 psi concrete mix for 10.5 yards of concrete. the ticket breaks down the weights of the amount of cement, stone, and sand used to make the 3500 psi concrete. the actual weights used to make this 10.5 yard load were: 1. cement = 5,805 pounds. 2..
