Properties of recycled ceramic aggregate concretes: Water resistance

Water permeability is a durability indicator, for it quantifies concrete resistance to penetration by external agents, due to that water is one of the main carriers of aggressive substances. The present study explores whether substituting 20% and 25% recycled sanitary ware for gravel in coarse aggregate affects structural recycled concrete resistance to water. The findings reveal that the slightly higher porosity in the recycled concrete does not translate into greater permeability. These new recycled concretes, which prove to be as durable as the conventional material, will therefore perform well throughout their design service life. (C) 2013 Elsevier Ltd. All rights reserved.
