The main difference between the two is their size. They also vary in their source, applications, and in the most common materials used to make them. As their names suggest, fine aggregate is made out of smaller particles than coarse aggregates.
Aggregates are often used in construction as an inert filler contained within concrete. Aggregates can make up upwards of 80% of a concrete mix, so the size and properties of the aggregate being used can have a strong effect on the properties of the resulting concrete.
In general, any aggregate with particles sized smaller than 4,75mm is considered to be a fine aggregate. Coarse aggregates, therefore, are any aggregates composed of particles bigger than 4,75mm.
Sand is the most well-known and widely used fine aggregate. Meanwhile, common coarse aggregates include gravel, crushed stone, and recycled concrete.
