Estimate cement, sand, gravel and water for the concrete mix based on the selected ratio of each. The shrinkage factor, standard of 52%, accounts for the compaction of the parts when mixed together with water.

-Volume: Total volume of concrete to be mixed.

-Shrinkage: Shrinkage factor, as a percentage, accounts for the loose parts compacted to yield the total volume needed. Default is set to a standard of 52%.

-Sand: Ratio of sand, in parts, to the total mix.

-Cement: Ratio of cement, in parts, to the total mix.

-Aggregate: Ratio of aggregate, in parts, to the total mix.

-Sand: Volume of sand for this mix.

-Cement: Volume of cement for this mix.

-Aggregate: Volume of aggregate for this mix.

-Water: Total gallons or Liters of water for this mix.

Estimate cement, sand, gravel and water for a concrete mix based on a standard ratio of 1 part sand, 2 parts cement, and 4 parts of aggregate to yield a total of 12 cubic yards of concrete.
