That is the average size of the stones in aggregate. They are commonly 1/4 , 1/2 , 3/4 and 1 inch.
The average size of fine aggregate is typically measured using a sieve analysis, where the aggregate is passed through a series of sieves with different mesh sizes to determine the distribution of particle sizes. For coarse aggregate, a similar sieve analysis is conducted, but it often involves larger mesh sizes. The average size can be calculated by determining the weight of aggregate retained on each sieve and then using these weights to find a weighted average particle size. Additionally, tools like the geometric mean can also be employed for more precise measurements.
There are two different types of aggregates namely,Fine aggregates - size of the aggregate is less than 4.75 mmExample : SandCoarse aggregates - Size of the aggregate is more than 4.75 mmExample : Gravel
For plain cement concrete, the aggregate used is of size 20 mm. For RCC structures, it is 40mm and for roads, it is 80mm

Distribution of soil particles for identifying the type of soils ie., wherther it is well graded or uniform graded or poorly graded soil.And also fine sand, medium sand coarse sand or fine gravel, medium gravel, coarse gravel etc.
Larger the size of aggregate will decrease strength of the concrete because surface area of this aggregate is low.Lesser the size of the aggregate will lead to increase the strength of the concrete.Well graded aggregate have all size of particles hence particle interferance is neglected,thus strength of concrete is more.
Nominal size is the size of the largest aggregate in a grading.
well-graded aggregates need less water.

Eggs graded AA (Grade AA) have a volcanic meaning in terms of size, with the largest eggs being referred to as "jumbo" in the United States. This grading system indicates the size of the egg and not necessarily its quality in this context.
Graded deposits are a type of sorted deposit. Graded deposits have particles that are sorted by size, with larger particles settling out first followed by smaller particles. This results in layers of sediment that are sorted by particle size within the deposit.

The word "grading" refers to the diversity in size of the aggregates. Aggregates that have "good grading" or are "well graded" have the same % of each size stone. The goal is to get the maximum aggregate packing density within a mix that still allows the cement to bond to the aggregates and cure properly, since its the aggregates that give concrete its high compressive strength.
