“…de Brito, 2007, Gomes and) studied the viability of incorporating coarse aggregate from concrete waste and ceramic block waste in the production of new concretes, and found that structural concrete made using recycled aggregates presented satisfactory durability, but that the 4-32 mm fraction of natural aggregates cannot be totally substituted. Lastly, Guerra et al (Guerra et al, 2009), López et al (Lopez et al, 2007) and Juan et al (Juan et al, 2007, Valdes et al, 2010 studied the mechanical and physical properties of concretes in which conventional coarse aggregate had been partially substituted by coarse ceramic aggregate obtained by crushing ceramic sanitary ware, and natural fine aggregate had been substituted by powdered ceramic material, obtaining satisfactory results in both cases.…”
