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%.
