· Coarse Aggregates. Coarse aggregate, within the realm of construction materials, encompasses a granular substance characterised by larger particle sizes. These aggregates typically comprise stones, gravel, or crushed rocks exceeding 4.75 millimetres (0.187 inches) in diameter. They fulfil a pivotal role in conferring strength, stability, and

· To provide clarity and avoid confusion, we will stay with the definition that gravel cannot refer to crushed stone and must remain in its natural state. There are three types of natural rock and stone: igneous, sedimentary, and metamorphic. Igneous: Igneous rocks are formed after molten rock or lava solidifies.

Aggregate, is a broad word that describes a “granular material used in construction” (granular meaning particles that do not stick together). Typically, aggregate material is extracted from quarry sites using heavy machinery, and crushed to produce varying sizes. This can be filtered out by size to be used in various applications that we

· Uses of Aggregates. Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as dynamic) load, to distribute the load properly to the supporting ground and to drain the water off the surface. In concrete the aggregate is used for economy, reduce

· Sand is broken down into two different types: fine and coarse. Fine sand is used as a filler and bulking material in construction due to its small size and ability to be packed tightly. This allows it to fill in the empty spaces other construction aggregates like gravel can’t. Coarse sand is used as a primary component in concrete mixtures.
