The size of fine aggregate is defined as equal to or less than 4.75 mm. This means that the aggregates that can pass through a number 4 sieve with a mesh size of 4.75 mm are referred to as fine aggregates. These include clay, silt, and sand. Crushed gravel and crushed stone can also fall under this category.

What Can Fine Aggregate be Used for in Construction? Fine aggregate, also known as sand, is a crucial component in the construction industry. It is widely used in the production of concrete …
