When you use a smaller aggregate, such as the 10mm as your nominal coarse aggregate size, the specific surface area of the total volume of coarse aggregate is much higher than for the 20mm aggregate. This means that your mix will require more cement, more water and more fine aggregate in order to provide adequate paste …

Size of Fine Aggregate Is. The size of fine aggregates is defined as 4.75mm or smaller. That is, aggregates which can be passed through a number 4 sieve, with a mesh size of 4.75mm. Fine aggregates include things such as sand, silt and clay. Crushed stone and crushed gravel might also fall under this category.

Size: The size of coarse aggregate is typically measured in millimeters, and it can range from 4.75 mm to several inches in diameter. The most common sizes of coarse aggregate used in concrete are 20 mm, 16 mm, and 12.5 mm. Shape: The shape of coarse aggregate can also have an impact on the properties of the concrete.

2.2. Well-Graded. Well-graded aggregates, also known as continuously graded aggregates, contain a balanced distribution of particle sizes, including all or most of the required sizes. This type of grading is preferred in general construction projects, as it results in a mix that is dense and well-compacted.
