Mineral rock wastes are being widely investigated due to possible damage to the environment when discarded indiscriminately in the nature, but also because of their great potential as ceramic raw materials. This work aims to study the effect of steatite particle additions on the mechanical properties of clay composites. A comprehensive series of experiments have been conducted to assess the influence of: steatite particle size, steatite fraction and compacting pressure on the performance of clay composites. The composite of superior properties was manufactured with 20 wt. (%) of steatite, 100-200 US-Tyler of steatite particle size and 30 MPa of compacting pressure.
