Incorporation of quartzite fines in the production of red ceramics

Journal of Cleaner Production, 2021
Abstract The ornamental stone sector produces a substantial amount of solid waste and effluents that are discarded in a disorderly manner, a fact that has prompted the need for research aimed at reuse. Considering the concepts of sustainable development and conscious mining, this study proposed the incorporation of quartzite residues in the ...

Degradation of Red Ceramic with Incorporated of Petroleum Waste

Materials Science Forum, 2014
The red ceramic pieces Campos-RJ degrade easily when they are in the built environment. With the intention to reduce the degradation in these pieces, was introduced petroleum coke in red ceramic. Petroleum coke is a solid fossil fuel, black in color and about granular form.

Red emission in Pr doped CaBi4Ti4O15 ferroelectric ceramics

Materials Science and Engineering: B, 2011
Abstract In this paper, Pr doped CaBi 4 Ti 4 O 15 ceramics were prepared by a traditional solid state method. Crystal structure and morphologies of the ceramics were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photoluminescence properties of the samples were investigated by a spectrofluorometer.

Red Ceramic Wastes: A Calcined Clay Pozzolan

2015
The properties and hydration of blended cements containing from 8 to 40 % by mass of ceramic waste (CW) from different countries (Argentine and Czech Republic) are investigated. The mini slump, the heat released rate up to 48 h, the pozzolanic activity and the compressive strength at 2, 7 and 28 are determined. Hydration process is characterized by XRD
