The final disposal route of post-consumer recycled glass (RG) is a common issue for many municipalities worldwide. Approximately 1 million tons of glassware is produced per year in Brazil, only 47% of which are currently recycled. The idea of incorporating RG as aggregate for concrete emerged in the 60´s motivated by some of the advantages of glass, i.e. low water absorption, high abrasion and durability, aesthetic potential among others. However, the initial researches have shown that concretes containing RG exhibited marked strength regression and excessive expansion due to alkali-aggregate reaction (ASR), which limited further research. The topic emerged again in the 90´s, imposed by the sustainability issues. Moreover, new studies aimed to determine the conditions at which ASR does not occur, as well as the influence of RG on the physical properties of concrete. Despite some literature on the use of RG into concrete, its application for making concrete roof tiles is still not documented. The incorporation of RG into those products, if feasible, may create a sustainable material for construction by reducing the land-filling of RG in
