1. Novel Artificial Ornamental Stone Developed with Quarry Waste in Epoxy Composite
Ornamental stones, such as marble and granite, are worldwide used as pavement cover and lining parts in civil construction. Dwindling deposits and environmental pollution, due to extraction methods, have motivated the replacement of natural ornamental stones by synthetic ones. In particular, artificial ornamental stones are being developed with mineral waste

2. Determination of parameters of the polishing in three types of granitic rocks / Determinação de parâmetros do polimento, em três tipos de rochas graníticas
The ornamental stones polishing in the industry is considered an empirical process. In this process, variables such as time, rotation speed and intensity of the load applied are combined in different operation conditions to obtain the desired brightness. Using the Polishing Rocks Simulator (SPR), this present research aims to obtain information about which c

3. Parâmetros técnicos para o aproveitamento ornamental dos granitóides Jaguari e Santa Rita, Região de Ibaré, Oeste do Escudo Sul-Rio-Grandense
The Jaguari and Santa Rita Intrusive suites crop out in the Ibaré region, Southwestern of Sul-rio-grandense Shield, around 340 km from Porto Alegre, Rio Grande do Sul State. These stratigraphic units contain granites of Brasiliano Cycle, which are research to aim ornamental stones. The studied granites occur in boulder fields and pavements. The granulation,

4. Análise tecnológica dos granitos Cerro do Sandi e Bela Vista, Piratini-RS para uso como rocha ornamental
Cerro do Sandi and Bela Vista granites occur in the Piratini region and belong to Dom Feliciano Suite. This suite is the most recent magmatic episode of the Pelotas batholith construction. The granitic massifs have elongate forms along NE-SW direction and constitute a positive relief of aligned crysts. Mapping of geological, structural and superficial deposi

5. Análise estrutural no planejamento de lavra de rocha ornamental
A análise estrutural de um maciço rochoso é uma importante ferramenta a ser aplicada ao planejamento de lavra de rocha ornamental. Além do mapeamento das descontinuidades, é importante definir-se como estão distribuídas as tensões no maciço rochoso. Nesse trabalho, apresenta-se uma análise estrutural do Sienito Piquiri, RS, com aplicação no plane

8. GLASS AND GLASS-CERAMICS WITH HIGH METAL CONCENTRATION OF FROM INDUSTRIAL WASTES / Vidros e vitrocerâmicos com alta concentração de metais obtidos a partir de resíduos industriais
The reuse of industrial waste materials is considered as an important source of raw-materials to be employed at new products. However proper criteria is needed in order to obtain vitreous materials from industrial solid wastes like solid galvanic waste (metallurgical industry) as main raw material. Ajusting the composition silica fine powder (ceramic industr
