New sustainable technology for recycling returned concrete
Highlights The new technology transforms returned concrete into a granular material. After curing, the granular material can be used as aggregates for new concrete. Consumption of natural aggregate is reduced and no waste is produced. Concrete with 100% of new aggregates has been developed and marketed in Japan.
Abstract A new technology is presented for transforming returned concrete into a granular material that can be reused as aggregates for concrete. The new method is based on non-toxic, easy to use additives that are added directly into the drum of truck mixers containing returned concrete. The new method favours the preservation of natural resources, allows the reduction of waste and the cutting of costs, both for waste disposal and for aggregates supplying. A laboratory and full scale test program has been undertaken in Japan by GNN, a Japanese association of RMC companies, to implement and fully assess the new technology.
