  • Microwave-assisted beneficiation of recycled concrete

    2011-8-1 · Recycled concrete aggregates (RCA) are produced by reducing the size of concrete debris through multiple crushing stages. Depending on the size, the crushed concrete particle may comprise one or more particles of natural coarse aggregate held together and surrounded fully or partially by a layer of mortar (Fig. 1a and b).In the present study, such RCA particles are referred to as Type I RCA.
