Fundamentals of Concrete - USDA

ratio of the weight of free-water in the mix to the weight of cement in the mix. It is computed on a weight basis by simply dividing the weight of the water in the mix by the weight of the cement in the mix. For example, for a mix containing 282 pounds of water and 564 pounds of cement the water-cement ratio would be: w/c = 282 lbs / 564 lbs = 0.5

Column Diameter - an overview | ScienceDirect Topics

Rules as related to column diameter include the following four rules: • The length to diameter ratio should be less than 30, preferably below 20, and tower height is to be limited to 60 m because of wind load and foundation concerns.If the tower is higher than 60 m, then a design with smaller tray spacing should be considered. The ratio of tower diameter to random packing size is greater
