13. Valorização de resíduos industriais como fonte alternativa mineral : composições cerâmicas e cimentíceas
This present work describes studies of valorization of wastes as alternative raw materials. Different industrial wastes, based on the SiO2-Al2O3-CaO system and classified as non-hazardous, were selected: Al-rich anodizing sludge, sludge from the filtration/clarification of potable water, sludge generated in ornamental stone-cutting processes, and foundry san

14. High performance latex-modified lightweight aggregate concrete for thin precast components - dosage, production, properties and microstructure / "Concreto leve de alto desempenho modificado com SB para pré-fabricados esbeltos - dosagem, produção, propriedades e microestrutura"
This dissertation deals with the application of the high performance lightweight aggregate concrete (HPLWAC) for the production of thin precast components, such as structural and insulation panels and elements for covering. A concrete with special properties was presented, once the use of styrene-butadiene latex (SBR), silica fume, accelerating superplastifi

15. Study on the possibilities of recycling of wastewater treatment wastes generated in the Metropolitan Region of São Paulo. / Estudo das possibilidades de reciclagem dos resíduos de tratamento de esgoto da Região Metropolitana de São Paulo.
The objective of this work was to investigate the options for the management of wastes generated from wastewater treatment plants, which were technically, environmentally, socially and economically feasible. The wastewater treatment process generates non-inert solid wastes among which the sludge is the most significant due to the amount produced. In the Metr

17. La roca magica: Uses of natural zeolites in agriculture and industry
For nearly 200 years since their discovery in 1756, geologists considered the zeolite minerals to occur as fairly large crystals in the vugs and cavities of basalts and other traprock formations. Here, they were prized by mineral collectors, but their small abundance and polymineralic nature defied commercial exploitation. As the synthetic zeolite (mole
