Highlights The ceramic waste analysed from the sanitary ware industry. This waste is used as a coarse aggregate in the manufacture of structural concretes. The durability to freeze-thaw cycles of these concretes is better than convectional concretes. ITZ of the new aggregate/paste is more resistance than natural aggregate. The recycled ceramic aggregate improve the quality of new concretes.
