Evaluation of the use of TiO2 industry red gypsum waste in cement production

Publicada en por admin

Abstract This work analyzes and evaluates the main mechanical, elastic and thermodynamic properties of cements manufactured with different proportions of red gypsum (RG), a waste generated by the titanium dioxide industry. The results show that red gypsum can be used as a safe substitute for natural gypsum in the manufacturing of commercial cements with no Read more about Evaluation of the use of TiO2 industry red gypsum waste in cement production[…]

Thermal characterization of new fire-insulating materials from industrial inorganic TiO2 wastes

Publicada en por admin

Abstract Two wastes, red gypsum (RG) and unattacked ilmenite (known as tionite), from the titanium dioxide production industry have been used to study the possibility of manufacturing new fire-isolating materials, and for that they were characterized for mineralogical composition and thermal behavior. Tests have demonstrated that these wastes could be used for fire insulation. Thermogravimetry Read more about Thermal characterization of new fire-insulating materials from industrial inorganic TiO2 wastes[…]
