Nominal maximum size. The largest sieve that retains some of the aggregate particles but generally not more than 10 percent by weight. Superpave defines nominal maximum aggregate size as "one sieve size larger than the first sieve to retain more than 10 percent of the material" (Roberts et al., 1996 ).
A gap is where the aggregate mix completely passes through one or more of the sieves within the aggregate range. This is a stricter requirement than ASTM's. For example, ASTM C 33 allows the #467 stone to leave no material retained on the 25.0 mm (1-inch) and 12.5-mm (0.5-inch) sieves.

Single-size aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is retained in the next lower sieve. A graded aggregate contains more than one single-size aggregate. Size of Coarse Aggregate Size of the gravel .

On Aggregate Grading ... size coarse aggregate used in this study.) If it didn't meet both requirements, we defined a combined aggregate as ... (9.5 mm) sieve divided by the weight of the material retained above the No. 8 (2.36 mm) sieve, expressed as a percent. Workability factor is the weight of the material passing
The effects of aggregate type, size, and content on the behavior of normal and high-strength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed. The concrete mixtures incorporate either basalt or crushed limestone, aggregate sizes of 12 mm ('h in.) or 19 mm (:Y. in.), and
AGGREGATE SIZE (following description of system and example are colour coded to aid understanding) Sizes are described in terms of a lower limiting sieve size, "small" d, and an upper limiting sieve size, "big" D. Written as d/D [note the slash is just a separator, it is not little d divided by big D].
We specialise in small to medium size contracts. By working closely with our customers, Morris & Perry ensure that we can supply the product is the most suitable for their use. All of our aggregates are supplied loose, on either 6 Wheeler (16T) or 8 Wheeler (20T) lorries.
The maximum size of coarse aggregate that can be used in a mix depends on the size, shape, and reinforcing of a member, based on these "not-to-exceed" guidelines (see Photos 5 and 6): 3/4 of the clear spacing between rebar or between rebar and forms (cover distance)
By the CT 382 definition, the maximum aggregate size is 3/4" and the nominal maximum aggregate size is 1/2". In the November 2011 version of CT 202, nominal maximum aggregate size is defined as "one sieve size larger than the first size to retain more than 10%."
Generally the size of coarse aggregate used is 10-12.5 mm. If we use the proportional mix of different sizes small to large (>4.5 mm to 20/25 mm), this make the concrete structure compact by align themselves in voids depending upon their size and compact mass will be formed with increased strength.
A coarse aggregate which has the sizes of particles mainly belonging to a single sieve size is known as single size aggregate. For example 20 mm single size aggregate mean an aggregate most of which passes 20 mm IS sieve and its major portion is retained on 10 mm IS sieve.

coarse aggregate used in pervious concrete is typically single size rounded river gravel or a crushed stone. Tennis et al. (2004) has reported that to manufacture pervious concrete, course aggregate is kept to a narrow gradation. Coarse aggregate having 9.5 mm top size has been used extensively for parking lot and pedestrian application.

Classification of Aggregates Based on Size. Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates.
