RBS | Aggregate
Aggregate. Sizes smaller than ¼" are referred to by the number of openings per inch that they will pass thru; a ¼" size is a #4, a 1/40 th " is a #40 and a 1/200 th " is a #200. AASHTO, the American Association of State Highway and Transportation Officials, specifies many standard sizes of crushed stone used by many state DOTs.

Aggregate in Concrete The Concrete Network
Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix. Economy is another reason for thoughtful aggregate selection. You can often save money by selecting the maximum allowable aggregate size.

Aggregate size| Concrete Construction Magazine | Concrete ...
The larger sizes will require less mixing water and hence, for a given cement factor, will produce concrete of lower waterratio than the smaller sizes. 3. The advantage of small aggregate in the waterratio strength relationship may or may not be sufficient to offset the effects of its higher mixing water demand.
