No Slump Concrete

No Slump Concrete

No Slump Concrete

(OP)
No Slump Concrete, is it the same as the following terms?

Zero-Slump
Dry Cast
Roller Compacted Concrete

Are there any other terms for no slump concrete?

RE: No Slump Concrete

Zero slump is the appropriate alternate term.  Dry pack is a hole packing or baseplate packing procedure that usually applies to grouts.  Roller compacted concrete does not have to have a zero slump.

RE: No Slump Concrete

Zero slump is also commonly used internationally.

It is commonly used in the production of different concrete products.

The main difference is the critical gradation of the aggregates, which are far more specific than current ASTM standards.

Zero slump concrete is not dependent upon the cement content, but upon the gradation and moisture content and in some cases the aggregate form (rounded, cubic or angular) and the amount of moisture. Vibration and compaction is critical. - It is similar to a traditional soil compaction with the addition of a cementing material(s).

This class of concrete is used in small amounts for packing and grouting, but is important in millions (billions?) of cubic yards of finished concrete materials.
