So much machinery, time and labor is involved in the creation of crushed aggregate that it can become a very expensive product. Despite the cost, aggregate products are the main component of concrete construction. In the majority of cases, crushed aggregate is used locally to prevent further costs being incurred in transporting the material.

Recycling crushed concrete to be reused helps reduce landfill crowding AND saves more resources from being used to create new concrete. Old concrete can be crushed down to specific sizes, cleaned so that unwanted debris is removed from the mixture, and reused as a solution to a number of construction and landscaping problems.

Concrete Sand is one of the types of sands in India that is made from crushed concrete. It is a common component in cement and asphalt mixtures. This sand is crushed in the quarry and filtered to remove the large rocks and huge fragments. It is a type of coarse sand that can be mixed with cement and water and then used as leveling base for layers, patios, and walking paths. When mixed with

Crushed concrete aggregate is used in construction projects such as bridge foundations, soil-cement pavement bases, airport runways, and oil and gas civil construction projects. It is also used for pavements, shoulders, and sidewalks. In addition, it can be used for making structural grade concrete, lean-concrete, and bituminous concrete.

Additional processes and equipment, such as water flotation, separators, and magnets, may also be used to remove specific elements from the crushed concrete. An alternative method is to pulverize the concrete, but this is not the always the best option, as it makes it harder to complete the separation process and may leave more contamination from smaller byproducts.
