Types of aggregates include Coarse aggregate and fine aggregate. The aggregate of each type is further sub-divided into many types and classification based on its size. The technique of Sieve Analysis is used for gradation of aggregate for use in concrete and for other applications. Aggregate is called bound material when it is mixed with

Fine Aggregate is aggregate less than 5mm. Can be a single sized material typically 20mm, 14mm, 10mm,or 7mm or a graded aggregate consisting of a blend of single sized aggregate.

Gravel is often used as an aggregate in concrete. Man-made gravel, like crushed rock and crushed stone, can come in a variety of sizes. When making these types of gravel, natural stone is mechanically broken up and sifted through different-sized mesh screens.

Size, for one thing. Each type of gravel is associated with a particular size of rock. Jersey Shore Gravel, for instance, is usually composed of rocks around ¾” in diameter. The other determining factor in gravel type is composition. Some gravel products are made only of rocks, while others have materials such as sand, clay, or stone dust

Aggregate gradation is also critical for achieving good packing and minimal porosity in an aggregate mix. The maxi- mum size of aggregates, the size distribution, and the shape of the particles determine the packing density that can be 13 derived with an aggregate sample, assuming sufficient com- paction is provided.
