Microwave-assisted beneficiation of recycled concrete

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).

Microwave-assisted beneficiation of recycled concrete

The main problem in using recycled concrete aggregate (RCA) as a construction material is due to the weak adhered mortar which usually has higher porosity and water absorption. It also has lower strength compared to natural aggregate (NA), and it often forms weak interfacial transition zones in the recycled aggregate concrete (RAC).
