How to Choose Quality Coarse Aggregate for Concrete Construction?

In order to select good quality coarse aggregates, engineers should consider the following crucial points: The typical coarse aggregate size ranges from 4.75 mm to 18 mm. Gravel or broken stone aggregates with rough and non-glassy texture are the best aggregates because they create a good bond with the cement paste.

What Is Fine Aggregate | Types of Fine Aggregates (Classification)

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.

The Effect of Aggregate Properties on Concrete

Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.
