摘要：
The recycling of mineral wastes is considered today an activity of utmost importance, contributing in the diversification of products, reduction of final costs, besides promoting alternative raw materials for some industrial sectors. This work focuses on the incorporation of steatite wastes in cementitious composites. A full design of experiment was carried out in order to investigate the effect of the experimental factors: fraction and particle size of steatite and compaction pressures (10 and 30 MPa) on the mechanical properties of the ceramic composites. The increase of the steatite fraction provided an increase of the bulk density and apparent porosity of the composites. Large particles of steatite provided an increase of the apparent porosity decreasing the mechanical strength. The increase of the pressing compaction decreased the apparent porosity, increasing the bulk density and the mechanical strength of the composites.
