| Abstract |
This study aims to evaluate the reuse of clayey quarry sludge generated during the washing process of aggregates in crushing plants as a raw material in ceramic bricks production. The representative sludge samples were collected from three quarries (S, G, and B) in Marrakesh region (Morocco). Different analytical techniques were used to investigate their mineralogical, chemical and physical properties. Ceramic pastes were elaborated using binary formulations based on the incorporation of each sludge at 0, 25%, 50%, 75%, and 100% with the conventional clay then sintered at 1050 degrees C. The mineralogical changes that take place during the incorporation of sludge were followed using XRD. The obtained results showed that the incorporation of sludge does not change the mineralogy of the fired bricks while the vitrification intensity increases. The sludge S and G can be used, at 100%, as an efficient substitute raw material, with a compressive strength of 20 MPa and flexural strength of 12 MPa. The optimal compressive and flexural strength were noticed to be about 36 MPa and 17 MPa, respectively, after the incorporation of 50% of sludge S. The total substitution by S and G as raw material in bricks manufacturing can contribute to the achievement of circular economy goals. [GRAPHICS] . |
