Fine aggregates consist of natural sand or any crushed stone particles that are ¼" or smaller. This product is often referred to as 1/4'" minus as it refers to the size, or grading, of this particular aggregate. What Is Coarse Aggregate? Coarse aggregates are a construction component made of rock quarried from ground deposits.

The shrinkage of no-fines concrete made with crushed limestone or river gravel is about half for that of conventional concrete. Investigations at CANMET have indicated that no-fines concrete prisms with no air-entraining agent were able to withstand up to 274 freeze-thaw cycles compared with 56 for prisms without an air-entraining agent.

The flakiness of the aggregate particles is of critical importance to the strength of no-fines concrete. The flaky particles can crush under load causing premature failure of the concrete. A flaky particle is defined as an aggregate particle with its least dimension less than 0.6 times its mean dimension (determined by sieving).

The fines, when laid to a depth of 4 to 5 inches, should bind to each other in a consolidated slab which is porous yet resistant to water falling on the surface.

2 tons (approximately 1 cubic yard) of crushed concrete was not enough to cover my 90 square feet to a depth of 4 inches; I probably ended up putting down 3 tons. Since the patio was positioned next to a concrete sidewalk, I used an 8' 2x4 with a piece of scrap wood nailed to one end which gave me a depth of 3 inches (the sand and paver depth).

No-fines concrete is a concrete mix design that does not contain fine aggregates (sharp particles of sand and crushed stone that are less than 9.55mm in diameter). By removing fine pieces of aggregate, the concrete becomes lower density and permeable, as the gaps between the coarse aggregates remain open, rather than being filled.

Probably self compacting #57, which is 1/2 to 3/4-inch gravel is generally considered to be self compacting.
