Classification of Aggregates Based on Size
These materials include gravel, sand, or crushed stone mixed with water which is all added to the cement mixture to create concrete. The most common size of aggregate used in the concrete mix is 20 mm for coarse aggregate and particle size less than 4.75 mm for fine aggregate.

Different Types & Sizes of Aggregate for Concrete » Engineering Basic
Fine Aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it. Natural sand is generally used as fine aggregate, silt, stone dust and clay also come under this category. The purpose of the fine aggregate is to fill the voids in the coarse aggregate and to act as a workability agent.

Fine aggregates are any aggregates less than 4.75mm in size per piece. This includes sand, silt and clay. Stone and gravel can also be crushed to the size of sand particles. Sand is the most common fine aggregate, often called a ‘soft deposit’ when used. Silt and clay usage is often called a ‘loam.’ Clay is usually smaller than 0.002mm in size per piece; silt is 0.002-0.06mm; fine sand

These grades are determined based on the size of the stone after it has been crushed, and they let you know the best applications for the specific stone. It is important to note that some gradations will have a range of stone sizes in that particular gradation. For example, a CA11 or CA7 (generally ¾”) gradation may include individual stone sizes of 1” down to ½”.
