Microstructural Evaluation of Clayey Ceramic Incorporated with Sludge from Paper Manufacturing

Article Preview

Abstract:

This work has for objective to evaluate the microstructure of clayey ceramic incorporated with a waste in the form of sludge generated during treatment of effluent of a paper making industry. The microstructure of ceramics incorporated with 0 and 10 wt.% of waste, and then fired at 600°C, was evaluated by optical microscopy, scanning electron microscopy and X-ray diffraction. The results showed that the waste changes the microstructure of the clayey ceramic increasing the porosity, as well as forming new crystalline phases, mainly with calcium compounds.
