Add water = free-water shown on the mix design – aggregate free-water For example, consider a concrete mix design that calls for 282-pounds of water (i.e. free-water) and contains 1100 pounds of fine aggregate and 2000 pounds of coarse aggregate. The mix design shows fine aggregate absorption to be 2% and coarse aggregate absorption to be 1%.

• ### How Thick Does Concrete Need to Be to Hold Up Weight? | Hunker

Structural concrete work is planned to bear loads, or hold weight, but transfer the weight to the soil base beneath the structure. The thickness of concrete is an important factor in load-bearing strength, but to conserve resources and avoid over-building, other factors are also taken into consideration.
