The technical feasibility of the use of granite residues as raw material in the manufacture of ceramic test specimens, with additions of the Coal Mineral Combustion (PCC's) products as a reforestation phase, was studied. The materials used were White Wing granite (RGAB) and Coal Combustion Products (PCC), in concentrations of 0% w / w, 5% w / w, 10% w / w, 15% w / P of PCCs. For a characterization of the raw ma...
The process of combustion of mineral coal in power station generate waste or by-products (products of coal combustion, PCC's) potentially harmful to the environment. This study aims to identify us waste, the main chemical elements and all the major crystalline phases that contain them. The PCC's were milled in high energy mills and sintered at 1200 ° C for 2 hours. They were then submitted to characterization b...
Bottom ashes generated during combustion of a mineral coal from Colombia were characterized by X-ray fluorescence spectrometry and X-ray diffraction. The interest in this particular coal is due to the fact that it will be used by a thermal power plant in Ceara, Northeastern Brazil, where it could produce over 900 tons of different residues/combustion products every day. Results from Xray fluorescence allowed id...
O aproveitamento de resíduos do granito para a produção de revestimentos cerâmicos vem sendo proposto como uma alternativa para o desperdício de matéria-prima na indústria. Por outro lado, durante a queima de carvão mineral em termoelétricas, são gerados os Produtos da Combustão do Carvão Mineral (PCC´s). Tais resíduos têm sido estudados, por apresentarem aplicações na fabricação de cerâmicas. O objetivo deste ...
Os produtos da combustão do carvão mineral (PCCs) são resíduos que causam impacto ambiental, mas apresentam grande potencial de utilização no setor da construção civil na produção de argamassas e concretos. Esta pesquisa objetivou verificar a viabilidade da utilização dos produtos da combustão do carvão mineral em argamassas de assentamento e revestimento. Foi avaliada a pozolanicidade nos produtos da combustão...
During the burning of coal in power plants, are generated several types of waste, called combustion coal products (CCP's).Currently, these materials have been investigated by presenting several technological applications, such as in the manufacture of ceramics. This experiment studied the feasibility of adding CCP as reinforcement phase in ceramic parts fabricated from the residue of granite.Two batches of part...
The mullite is one of the most important ceramic compounds in terms of industrial applications. Formed by alumina, silica, mullite has unique properties, leading to their application in the ceramics industry. Obtaining mullite requires high temperature demand, in view of the high temperature phase formation (about 1500 ° C). This study aimed to applying the technique of high energy milling to obtain mullite fro...
Durante a queima de carvão mineral em usinas termoelétricas, são gerados vários tipos de resíduos ou subprodutos. Atualmente, tais materiais têm sido alvo de muitos estudos, por conter cinzas, além do fato de apresentarem diversas aplicações tecnológicas, como na fabricação de diversos tipos de peças cerâmicas. O objetivo deste trabalho foi estudar a viabilidade da adição de produtos da combustão do carvão mine...
The use of residues from the extraction of granite for the production of ceramic tiles has been proposed as an alternative to reduce the waste of raw material in the dimension stone industry. Moreover, during the burning of coal in power plants, are generated various kinds of waste or by-product called combustion of coal (CCP´s.). Currently, such materials have been investigated, by presenting various technolog...
