25. Analysis of Dimension Stone Waste Addition to the Clayey Mass Used in Roof Tile Production
Addition of dimension stone waste to clayey mass is an alternative to make the dimension stone sector more environmentally sustainable and to reduce the consumption of clayey raw material. Our aim is to study the technical feasibility of dimension stone waste addition to the clayey mass used in roof tile production. Samples of waste and clay were tested for

26. Evaluation of the milling efficiency increase of AISI 52100 steel using niobium carbide addition through high energy ball milling
The AISI 52100 is a tool-type steel and is more often used in industry for the production of bearings. After the end of its life cycle, it is discarded or remelted, but both processes are considered expensive. Thus, the possibility of reusing this material through the powder metallurgy (PM) route is considered advantageous, since it transforms a waste into a

27. Evaluation of the Incorporation of Waste Generated from Titanium Dioxide Manufacturing in Red Ceramics
Rotary-vacuum-filter mud (RVFM) is waste generated during the manufacturing process of titanium dioxide. In this work, RVFM and ceramic bricks containing different ratios of this waste are investigated. The mud samples were characterized using thermal analysis (TG/DTG). The aim of the present work was to determine the effect of adding RVFM on the ceramic pro

28. Incorporation of ceramic waste into binary and ternary soil-cement formulations for the production of solid bricks
The incorporation of ceramic waste (CW) into solid bricks made with soil-cement mixtures has been studied in recent years. The aim of this study was to evaluate the physical and mechanical properties of solid bricks made with soil-cement mixtures uniaxially pressed with the addition of construction waste, having hydrated lime and CPII F-32 Portland cement as

29. Comparison of polymers and ceramics in new and discarded electrical insulators: reuse and recycling possibilities
The expansion and maintenance of electricity distribution networks generates large amounts of waste, much of it in the form of discarded insulators that are not reused or recycled. This paper describes the results of tests on used and new ceramic and polymeric insulators to verify if their exposure to weathering justifies their replacement. In new and used c

30. Application of bauxite waste from amazon region in the heavy clay industry
In this work, a method was developed for the application of red mud, an alkaline leaching waste, from a bauxite processing plant located in northern Brazil (Amazon region) as starting material for heavy clay products. Samples were prepared by pressing blends of red mud and clay, which were then fired at temperatures from 900 ºC to 1190 ºC. Characterization

31. Study of mechanical properties and durability of magnesium phosphate cement matrix containing grinding dust
The acid-base cements are materials developed by means of reactions between an acid component and another basic one. This type cement belongs to the family of the so called "chemically bonded phosphate ceramics" (CBPCs), new types of inorganic materials that have special physico-chemical properties and that, in contrast to most advanced ceramics, are made by

32. Efeitos de mineralizadores na produção de pigmentos cerâmicos de óxido de ferro resíduo e comercial em matriz de sílica amorfa / Eflect of mineralization in the production of ceramic pigments commercial and waste iron in amorphow silica matriz
A utilização de óxido de ferro na produção de pigmentos é justificada pela sua ampla variedade de cores, alta estabilidade térmica e atoxidade. Estes óxidos podem ser de origem natural ou sintética, sendo que atualmente vem ganhando espaço o uso de subprodutos industriais como fonte de óxidos pigmentantes. Já entre os processos para produção de

33. Avaliação de concreto auto-adensável com agregado reciclado de telha cerâmica / Evaluation of self-compacting concrete produced with the recycled aggregate tile
The increasing demand for raw materials in construction, especially those drawn from nature, is of great concern due to harmful impacts it produces. The use of recycled aggregates can be a sustainable and contribute to the preservation of natural resources, contributing to the sustainable development of the construction industry. The residue from the ceramic

34. Energetic use of wood waste in one center for the production of red ceramics in São Paulo State / Uso energético de resíduos madeireiros em um pólo de produção de cerâmicas vermelhas do Estado de São Paulo
The use of forest biomass is an important alternative of renewable energy source, economic, technical and environmentally viable, fighting for space with other energy sources, more expensive or non-renewable, such as natural gas, electricity, diesel and LPG. Within the industrial sector, biggest consumer of biomass energy, the segment of red ceramics represe

35. Vidro de sistema Li2O-ZrO2-SiO2 como alternativa para síntese de pigmento cerâmico contendo resíduo industrial rico em Fe2O3 / Synthesis of inorganic pigments from glass-ceramic system Li2O-ZrO2-SiO2 and waste from the metallurgical industry. 2012
Recentemente, na indústria cerâmica tradicional, tem havido um interesse crescente na obtenção da inclusão de pigmentos na qual a temperatura de queima seja estável de tal forma que ação dos vidros fundidos não interfiram no produto final. No setor de revestimento, cuja seleção é fortemente influenciada pelo aspecto visual da superfície decorada

36. Blocos para execução de alvenaria de vedação empregando garrafas pet: avaliação mecânica e termoacústica
Recycling and reuse of materials is the most evident solution regarding sustainable development. One relevant aspect to this development refers to the integration of engineering to devise ways that enable the reuse of materials considered as waste, but with great potential of applicability in the building industry itself, through the generation of appropriat
