Popis: Abstract Red ceramic waste (RCW) is one of the main by-products generated by the production of ceramic materials. Its application in lightweight aggregates (LWAs) has not yet been tested. Thus, this review intends to evaluate the perspectives of using RCW in the manufacture of LWAs. The search was carried out in the ScienceDirect database. 47 articles were selected. A significant amount of data on the chemical, physical, mineralogical, and morphological properties of RCW are discussed. In most studies, the chemical constituents of RCW complied with the swelling parameters. The mineralogy of the residue usually has constituents capable of controlling the viscosity and aiding gas formation. The data of granulometry, microstructure, and loss of mass denote the need for special care with the methodology adopted for grinding and sintering of the residue. This review indicates that there is a high potential for the use of RCW in the manufacture of LWAs.
