Types of Aggregate: A Guide
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, andof coarse aggregates for road base construction from Arba Minch area of different quarry sites. 4.1.1.

The utilization of recycled aggregates is a good solution to the problem of an excess of waste material, provided that the desired final product will fit the standards. The studies on the use of recycled aggregates have been going on for 50 years. In fact, none of the results showed that recycled aggregates are unsuitable for structural use [4].Concrete is one of the versatile and widely used building materials in the world Construction industry.
