1. Maximization of the use of casting sand residue in the production of fired ceramic bricks
Abstract In this study, a red ceramic was developed with the addition of sand residue from deburring and finishing processing of cast iron molds, replacing a variable fraction of the clay. The formulated masses were shaped by pressing and firing at different temperatures (850, 900 and 1000 ºC) at a heating rate of 180 ºC/h and 2-hour level. The bodies were

3. 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

4. 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

5. 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

7. Adição de cascalho de perfuração da bacia potiguar em argilas para uso em materiais cerâmicos: influência da concentração e temperatura de queima.
One of waste produced on large scale during the well drilling is the gravel drilling. There are techniques for the treatment of the same, but there isnt consensus on what are the best in terms of economic and environmental. One alternative for disposal of this waste and objective of this paper is the incorporation and immobilization of gravel clay matrix to

8. Numerical and experimental thermal analysis of a tunnel kiln used in ceramic production
The available technology for tunnel kilns in Brazil is practically empirical and there is a lack of fundamental studies developed as an aid for the design of new kilns or for the retrofit of old ones. Here, a thermal model of a tunnel kiln is developed allowing the numerical simulation of kilns and dryers aiming toward a more efficient and less energy consum

9. Desenvolvimento de bloco de vedação com barita na composição de partida para blindagem de radiação X
This work main objective is to study the use of bricks in barium X-rays rooms in order to contribute to the optimization of shielding rooms diagnosis. The work was based on experimental measurements of X-ray attenuation (40 to 150 kV), using ceramic seal bearing the incorporation of barium sulfat (BaSO4). Different formulations were studied in three differen
