13. Drying Contraction Assessment of Ceramic Products Produced by Extrusion or Pressing Formulated with Sheep Wool Waste
The main aim of this paper was to evaluate ceramic products containing a percentage of ash from sheep wool waste through drying linear shrinkage from a small brickyard in Bagé - RS. The ash percentages used in the formulation were 0, 5, 10, 20 and 30%. Raw materials were analyzed by Energy Dispersive X - ray Fluorescence (XRF/EDX). The methods used to shape

14. Calcined Clay Lightweight Ceramics Made with Wood Sawdust and Sodium Silicate
This paper aims to study the influence of including wood sawdust and sodium silicate in the production process of calcined clay lightweight ceramics. In the production process first, a sample used by a company that produces ceramic products in Brazil was collected. The sample was analysed by techniques of liquidity (LL) and plasticity (LP) limits, particle s

15. The Bond Strength Behavior of Polymer-modified Mortars During a Wetting and Drying Process
Polymer-modified mortars are highly popular for setting exterior tile systems and low-porosity ceramic tiles because they possess greater flexibility and higher bond strengths than conventional mortars which increases cladding serviceability. However, the long-term performance of this application is not completely understood and many pathologies has been rep

16. Incorporation of in Natura and Calcined Red Muds into Clay Ceramic
Brazil is one of the world greatest aluminum producer and also comprises a large industrial sector dedicated to the production of alumina (Al2O3) by the traditional Bayer process. During this process an insoluble residue, known as red-mud, is generated and normally discarded. A possible use for the red mud is its incorporation into clay ceramics. Indeed, thi

17. 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

18. Desenvolvimento e caracterização de microesferas de fosfato de cálcio bifásico / Development and characterization of biphasic calcium phosphate microspheres
The biphasic calcium phosphate is greatly applied in the replacement of osseous tissues and as dermal fillers due to its chemical similarity with the mineral part of bone and teeth. Due to this similarity, the calcium phosphates present, among other important properties, high biocompatibility, bioactivity and/or osteoconduction. They do not induce inflammato

19. 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
