How to Specify Concrete | Architect Magazine

The water-to-cement (w/c) ratio of concrete is calculated by dividing the weight of the water in a mix by the weight of the cement. Ratios typically range from 0.45 to 0.60. Since the two values are inversely related, the strength and durability of the concrete will increase as the w/c ratio decreases—that is, the lower the water content, the ...
