    Recycled concrete aggregate (RCA) are aggregates obtained by recycling clean concrete waste where content of other building waste must be very low – below few per cent. For instance, British standard BS 8500-2 ( BSI, 2006 ) defines RCA as recycled aggregate with maximum masonry/fines content of 5%, maximum lightweight material/asphalt content

    Jan 07, 2019 Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate. Additional processes and equipment, such as water flotation, separators, and

    Dec 10, 2018 Recycling concrete results in significant cost savings, while also reducing the environmental footprint of concrete waste and production. Instead of mining and transporting new aggregates for concrete production, recycled concrete can be used in its place, cutting down on energy use and fuel emissions involved in sourcing and transporting other

    Sep 27, 2020 Recycled aggregates are only classified as recycled concrete aggregates (RCA) when the primary material is concrete. By crushing and compressing existing waste concrete and combining it with aggregate, producers can create concrete aggregate to a specific size and quality, which makes it very cost effective to purchase

    Large machines break down concrete into aggregate for recycling. The Process Of Recycling Concrete. Commercial sites are where the bulk of concrete recycling is done. After a building or foundation is demolished, the concrete is typically hauled to a site and then broken down and crushed into small pieces by machines. The aggregate stones are

    Recycling also saves energy that would otherwise be used to mine, process, or transport new aggregates, which is also beneficial to the environment. Using a recycled aggregate also offers its own set of benefits. For instance, CA6 recycled is 15% lighter than virgin CA6, which means that you get 15% more volume per ton with your order
