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 favors 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. 000002060 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000002060 653__ $$aAggregates, natural resource protection, recycling, returned concrete, superabsorbant polymer, sustainability 000002060 7112_ $$aFirst International Conference on Concrete Sustainability$$cTokyo (JP)$$d2013-05-27 / 2013-05-29$$gICCS13 000002060 720__ $$aFERRARI, Giorgio$$iFERRARI, Alberto$$iMIYAMOTO, Mitsuya 000002060 8560_ $$ffischerc@itam.cas.cz 000002060 8564_ $$s1006542$$uhttp://invenio.itam.cas.cz/record/2060/files/S1-1-3.pdf$$y Original version of the author's contribution as presented on CD, . 000002060 962__ $$r2053 000002060 980__ $$aPAPER
