Recycled concrete - the future of construction For Recycled Concrete | RC concrete from mineral construction waste - for example that left over after the demolition of buildings - is prepared and used as aggregate. These treated materials replace the parts of gravel or crushed natural stones normally contained in concrete. The use of RC concrete is authorized both old crushed concrete and the use of masonry debris and tiles. This is why several colors are available and make the use of recycled concrete an interesting decorative element for architects. An active contribution to the protection of the environmentrécupération de béton The use of recycled concrete in architecture has a particular appeal: the old dismantled building is reflected in parts of the new one. With suitable surface treatment , the durability of the recycled concrete construction is therefore directly visible. What's more, the technology conserves natural resources while actively contributing to the protection of the environment. CIRCULAR ECONOMY Compression crushing technology recognized for more than twenty years for its performance on a wide range of minerals, in particular hard and abrasive, FCB Rhodax ® 4D is now being deployed in a new application for the recycling of deconstruction concrete. The unique selective grinding mode of this technology allows, on this application, an excellent release of the 3 fractions composing the concrete: the aggregate, the sand and the cement paste. Numerous tests have already been carried out for major players in the sector and the FCB Rhodax ® 4D will begin to industrially treat deconstruction concrete for the first time in the second half of 2022 for the HeidelbergCement group in Poland. The benefits of this unique link in terms of the circular economy are numerous, particularly in the face of increasingly demanding impositions on the recovery of products from deconstruction: reuse of aggregates and sand in new concrete, and reuse of cement paste in the cement process to produce a low-carbon clinker or as an additive to cement.

It is also planned to recarbonate the released sand and cement paste fractions with CO 2 captured from the cement works gases.
