Concrete Aggregate
Concrete Aggregate Sand
Concrete sand is a coarse washed sand with grains up to about 3/8 inch across. It's the sand you mix into concrete, and the wash step pulls out the silt and clay that would weaken a finished slab. The grains are angular and gritty, so they pack tight and hold their shape under a screed.
The "concrete" in the name points to ASTM C33, the spec that sizes the sand and stone used in ready-mix concrete. Concrete sand meets the C33 gradation for the sand portion, which is why concrete plants buy it by the truckload. You'll also see it called C33 sand or manufactured sand, and it costs a bit more than fill sand because of the washing and screening.

How to choose within concrete aggregate sand
Match the mix design
Batch plants and ready-mix trucks work to a spec. Confirm the size and gradation the plant is running before you order.
Coarse vs. fine
Coarse aggregate gives the mix its strength; fine aggregate fills the gaps. A slab needs both — usually delivered separately and blended at the plant.
Cleanliness matters
Fines and clay contamination weaken the cure. If a load looks dusty, ask for a wash spec sheet before you take delivery.
