1. Industrial Wastes as Alternative Mineral Addition in Portland Cement and as Aggregate in Coating Mortars
This paper presents an evaluation study of wastes from pulp and paper as well as construction and demolition industries for application in cement-based materials. The alternative raw materials were used as a source of calcium carbonate (CaCO3) and as pozzolanic material (water-reactive SiO2) in partial replacement of Portland cement. In addition to the hydra

2. Nano Coated Lead Free Solders for Sustainable Electronic Waste Management
ABSTRACT Lead has been used in a wide range of applications, but in the past decades it became clear that its high toxicity could cause various problems. Studies indicate that exposure to high concentrations of lead can cause harmful damages to humans. To eliminate the usage of lead in electronic products as an initiative towards electronic waste management

3. Waste disposal using a spreader and conveyor belt method
Abstract In the search for opportunities to decrease operational costs in iron ore mining, waste disposal by conveyor belt has been considered as an alternative. In this work, this form of waste dump is investigated by means of the construction of a test pile and the assessment of geotechnical characteristics such as shear strength and in situ densities. Res

4. Aceleração da consolidação em solos tropicais com drenos condutores elétricos / Acceleration of consolidation on tropical soil with electro conductor drain
The electrokinetic method has been studied by a growing number of research centers, in application such as mining engineering, civil and environmental engineering, food and sports. To meet the application needs it was necessary to develop a new technology that combines a variety of materials, functions and processes for the implementation of specific activit

5. tropical soils, bentonite, hydraulic conductivity, compatibility, barriers. / CONDUTIVIDADE HIDRÁULICA E COMPATIBILIDADE EM COMBINAÇÕES DE SOLO TROPICAL E BENTONITA PARA USO EM BARREIRAS
Barriers are key elements for the environmental protection in waste disposal sites. Additionally, compacted tropical soils have great potential to be used in these barriers, once some technical matters are correctly addressed, including low hydraulic conductivity and adequate compatibility to the disposed fluids. In this context, the bentonite addition in tr

6. Comportamento mecânico de resíduos sólidos urbanos / Mechanical behaviour of municipal solid waste
Este trabalho apresenta um estudo das propriedades de resistência e de deformabilidade dos resíduos sólidos urbanos (RSU). Amostras de resíduo de diferentes idades, obtidas no aterro metropolitano centro (Salvador-BA), foram submetidas a ensaios de compressão triaxial e de compressão confinada em equipamentos de grandes dimensões. Os resultados dos en

7. Interface strength between geomembranes and soils by ring shear test / Resistência de Interface entre geomembranas e solos através do ensaio de Ring Shear
This paper deals with the shear strength in the geomembrane-soil interfaces used in landfill and waste pond liners. Modified ring shear tests were carried out using sandy and clayey soils, in dry and saturated conditions. The tests were performed using a coarse to medium graded sand and a clayey soil from a sanitary landfill in Piracicaba - SP. In this work,

8. Mechanical behavior of urban solid waste / Comportamento mecânico de resíduos sólidos urbanos
This thesis deals with the mechanical behavior of urban solid waste from Bandeirantes sanitary landfill (São Paulo, Brazil). Field and laboratory tests, as well as data from field instrumentation (settlement) were obtained and used in the analysis. Results of in situ tests such as standard penetration test (SPT), cone penetration test (CPT), infiltration te
