What Is a Lean Concrete Mix and How Is It Made? - Engineer Calcs

Mar 29, 2021 · Important Note: for lean concrete mix, the Water/Cement (W/C) ratio is typically high. Typically, the W/C ratio is around 0.4 to 0.5, but I've seen as high as 1.1. This 1.1 W/C ratio helps maintain workability. For example, you can easily get the concrete out of a truck and pour it. Also, with lean mixes, you'll have less shrinkage of concrete.

What is the weight of concrete per cubic foot? - Everything About Concrete

The weight of concrete per square foot is going to depend on how thick the concrete slab is. If your square foot of concrete is 6 inches thick, you have to divide 6 (inches) by 12 (1 ft.) to figure out the thickness in feet. 6 / 12 = .5 feet. You know, from the information above, a cubic foot of concrete weighs 150 pounds.
