The principle of proportioning aggregate is that the smaller particle will fill up the voids between large particles. A well proportioned concrete mix requires a minimum amount of cement per unit volume.

  • 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. The batch plant operator measures the aggregate moisture and finds
