1. Evaluation of the Effect of the Incorporation of Blends of Fuel and Fluxing Wastes in Red Clay Ceramics
The clay samples endure the incorporation of industrial and urban wastes, which do not cause large variations in their properties if added in controlled quantities. Wastes can be classified as fuel, fluxing and property affecting wastes. The fuel wastes usually have a high amount of organic matter, that when heated cause exothermic reactions, releasing heat

2. Characterization of mineral wools obtained from ornamental rock wastes
Abstract The study aimed to characterize the mineral wools obtained from wastes of the cutting step of marble and granite, in order to evaluate the possibility of their use on an industrial scale. Mixtures of marble and/or granite wastes were prepared in order to reach the chemical composition of rock and glass wools. The batches were melted in an electric a

3. Use of ornamental rock residues for mould flux development
Abstract Ornamental rock production, such as marble and granite plates, have great importance in the southeastern region of Brazil. Its residues are composed of some compounds used in continuous casting as mould fluxes. Therefore, the aim of this article was to study these residues to formulate mould fluxes. First, the raw materials were chemically character

4. Development of Epoxy Matrix Artificial Stone Incorporated with Sintering Residue from Steelmaking Industry
The present work is part of an innovation research project aiming to develop artificial stone from industrial wastes. In principle, the project goal is to fabricate artificial stones with improved characteristics to be used as plates for housing and road construction. In this work, the specific industrial residue was an electrostatically precipitated powder

5. Recovery of Steelmaking Slag and Granite Waste in the Production of Rock Wool
Steelmaking slag and residues from granite cuttings are industrial wastes with considerable production, however limited applications. This work studied an inertization and recovery process of such wastes as raw materials into production of rock wool (i.e. a thermo-acoustic insulator with growing market). Several batches were produced aiming the chemical prop

6. Polishing Knowledge: A Study of Marble and Granite Processing
The aim of this article is to understand the work situations and highlight aspects of the knowledge invested by workers when performing marble and granite processing activities. The survey is qualitative and was based on the reality of a small industrial company that deals with processing activities. The case study was based on theoretical and analytical erg

7. Experimental investigations on mode II fracture of concrete with crushed granite stone fine aggregate replacing sand
With a view to implement sustainability concepts (namely, use of locally available materials and industrial by-products) in the concrete construction industry, the possibility of use of crushed stone fine aggregate as replacement to river sand is explored in this paper. Towards this, tests have been carried out on concrete cubes and concrete cylinders. The e

8. Controles geológicos das jazidas de granitos ornamentais da região de Encruzilhada do Sul: origem das variedades comerciais do granito Encruzilhada do Sul
In the region of Encruzinhada do Sul, it is common the exploration of three faciological varieties of Encruzilhada do Sul Granite: porphyritic, heterogranular coarse and heterogranular very coarse. These varieties are commercially known as Rosa Encruzilhada, Bege Pérola and Coral, respectively. The petrographic analyzes and spatial disposition of the studie

9. 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

10. Efeito de adições ativas na mitigação das reações álcali-sílica e álcali-silicato. / Effect of mineral admixtures in controlling the alkali-silica reaction and alkali-silicate reaction.
The alkali-aggregate reaction is a pathologic manifestation that can induce the premature distress and loss in serviceability of concrete structures affected. It is directly associated to the selection of materials (cement, coarse and fine aggregates, water and additives), as the interaction between these materials and environmental condition will grant the

11. Contribution to Crushed Stone Petrography / Contribuição à petrografia de pedra britada
It is extremely important to know the physical and chemical properties of aggregate mineralogical composition so that the construction where they will be used is not compromised. In this sense, knowing the petrography and mineralogy is as necessary as knowing the geology of the rock deposit to be developed as a source of crushed stone. The main purpose of th

With the decline of the mass production system, which had a predominant focus on big companies, there was a readjustment of the productive forces with tendencies to a structure that started to favor the small and medium companies (SMCs), mainly when they act in an united way in industrial clusters and not separately. Starting from the nineties, several studi
