In the present study, the use of granodiorite, as fluxing agent in a body mix for stoneware ceramic tiles production, was assessed. Fourbatches were formulated using clay from Khaboba, and natural granodiorite from Saint Katherine, Sinai, Egypt. The batches weretailored to completely replace both feldspatic and inert components of stoneware ceramic tiles. Densification was studied according toISO rules, while sinterability was estimated by optical dilatometry. The dependence of microstructure and mechanical properties ofstoneware ceramic tiles on granodiorite content was discussed. Strength measurements showed that increasing granodiorite content thebending strength of the bodies increased. In particular the studied batches can be used for the production of industrial fast firing tiles.The obtained ceramic tiles possess properties similar to commercial ceramic floor and/or wall tiles.
