The fabrication of conventional red clay ceramics products for civil construction, such as bricks and roofing tiles, normally uses other raw materials like sand, in addition to clay, as a way to condition the final ceramic properties. Quartzite residues, from ornamental stone processing in the northeast region of Brazil, could be used as possible conditioner material for clay body in a ceramic industry owing to its similar characteristics to common sand. In the present work, complementing a recent publication on the same materials, a quartzite residue was characterized and its potential as a red clay ceramic addition was evaluated for different composition up to 40 wt%. The results indicated economical advantages in association with some technical benefits. |
