Recipe for Concrete Mix without Aggregate: - 1 3/4 - 2 quarts of water - 5 quarts of sand - 2 1/2 quarts of portland cement In a mixing container (bucket) mix all dry ingredients together.The term dry-cast, also known as reconstructed stone or reconstituted stone, is simply as it sounds; to use a dry mix to cast, using moulds to manufacture man-made sandstone. Strictly speaking the mix used to make sandstone is not totally dry or it would not hold together.In the December 1969 (page 457) issue, the magazine reported briefly on a new concept called dry-cast concrete, which differs from conventional concrete mainly in that the introduction of water takes place after the mixture of portland cement and aggregates has been placed in the form and compacted and finished.

Precast Concrete Advantages versus Site-Cast
Dry-cast concrete is very dry (w/c of 0.30 to 0.36), has zero slump, and the forms can be stripped as soon as the concrete has been consolidated. Dry-casting requires an expensive dry-casting machine and is typically used for mass production of products like concrete pipe or manholes and also in concrete block production.Dry Cast- Uses a concrete mix with zero slump.
