Environmentally Sustainable. Arguably, one of the greatest advantages of recycled aggregate is the fact that it is environmentally sustainable. It typically uses far less energy during the production stages and eliminates the need for quarrying virgin material. In addition, virgin material deposits are where they are.

· Recycled Aggregate Concrete (RAC) is basically concrete mix that is prepared from crushed aggregates and concrete which has already been used in construction works. In the sector of construction engineering the key role of an engineer is to provide adequate quality products with the available materials.

· The recycling construction and demolition waste could have a positive net benefit compared to the procurement and production of virgin aggregate materials with the same properties. This is not only financially beneficial but also environmentally viable, as fewer resources would be required to produce the same aggregate material.

· In the current century, urbanization and the development of the construction industry have led to the generation of construction and demolition waste (CDW), imposing pressure on ecology and the environment. This has attracted the attention of industry personnel and researchers. This work discusses the current research on

· Recycled aggregate is considered a “green” construction material since it minimizes the amount of virgin aggregates produced and hence reduces the use of natural resources. In order to fulfill UK and sustainability targets, there is a rising demand on landfill capacity and on construction sites to divert trash away from disposal.

· Recycled aggregate is made up of crushed cement, asphalt, and granite. When a building is torn down or demolished, aggregate materials are collected from the waste, left behind at the demolition site. The resulting recycled aggregate can then be reused in projects, such as railroad track ballast, road surfacing, road construction,

Concrete pavement recycling is an environmentally sustainable choice in terms of energy and other life- cycle impacts. It can reduce the mining, use, and transportation of virgin aggregate, all of which saves energy and reduces emissions. It correspondingly reduces unnecessary consumption of limited landfill or stockpiling space.

· Concrete recycling to produce aggregates is crucial in reducing the demand for virgin materials in the construction industry, particularly for the most widely used building material—concrete. A potential solution to enhance the quality of recycled aggregates involves the removal of the adhered cement paste from their surfaces. In

· Using recycled aggregate s from construction and demolition waste can preserve natural aggregate resources, reduce demand of landfill, and contribute to sustainable built environment.
Consulta
· Recycling concrete can be used to produce recycled aggregates that reduce the need for extracting more and more natural aggregates, thereby, relieving stress on the natural resources available. Recycling concrete also offers economic benefits in terms of cost savings, particularly in case of large construction works.
