1. Technological properties of a self-bloating clay and expanded-clay aggregate for the production of lightweight concrete
Abstract The global interest in an increasingly sustainable economy, with a reduction in the consumption of raw materials and energy, can be supported by the growth in the use of lightweight concrete (LC) produced with expanded-clay aggregates (EA). The main qualities of natural self-bloating clay for the production of EA were studied, analyzing the paramete

2. Doxazosin adsorption in natural, expanded, and organophilized vermiculite-rich clays
Abstract Vermiculite clays are adsorbent materials that have good chemical adsorption capacity, which makes them applicable in the removal of drugs from aqueous solutions. Their lamellar structure can be easily expanded and organophilized. To assess the efficacy and environmentally-tolerant capacity of the adsorption method, the organophilized vermiculite cl

3. Avaliação do efeito do tratamento a plasma sobre a superfície de filmes de polietileno verde e argila vermiculita
RESUMO O Polietileno (PE) Verde é um polímero sintético que apresenta baixa energia superficial, que resulta em fraca propriedade de adesão. Esta baixa adesão, provoca alguns problemas relativos às aplicações práticas dos polímeros, como fraca aderência de tintas de impressão, revestimentos, adesivos e metais à superfície do polímero, entre ou

4. Investigation of the Wettability Using Contact Angle Measurements of Green Polyethylene Flat Films and Expanded Vermiculite Clay Treated by Plasma
Polyethylene (PE) is a polymer that has a low adhesion property, which is related to its low surface energy. However, the plasma treatment aims the modification of the surface properties without affecting the polymer structure. In this sense, the objective of this work was to prepare biocomposite films via flat extrusion with Green PE matrix and Expanded Ver

5. SIMILITUDE AND THERMAL PERFORMANCE ON NON-CONVENTIONAL ROOFS
ABSTRACT The objectives of this study were to evaluate the thermal comfort and the similitude between prototypes and reduced models, using non-conventional coverage with green roof and expanded clay aggregate, supported on wood frame structure. For this, were determined the Black Globe Temperature and Humidity Index (BGHI), the Human Discomfort Index (HDI),

6. Synergistic Effect of EG and Cloisite 15A on the Thermomechanical Properties and Thermal Conductivity of EVA/PCL Blend
The purpose of this study was to investigate the synergy of expanded graphite (EG) and Cloisite 15A (C15A) on the thermal conductivity and thermomechanical properties of ethylene-vinyl acetate copolymer/poly ( ɛ-caprolactone) (EVA/PCL) blend. Scanning electron microscopy (SEM) results showed that the blend had a phase separation, in which the PCL phase (app

7. Characterization of the biomass of a hybrid anaerobic reactor (HAR) with two types of support material during the treatment of the coffee wastewater
This study investigated the microbiology of a hybrid anaerobic reactor (HAR) in the removal of pollutant loads. This reactor had the same physical structure of an UASB reactor, however with minifilters inside containing two types of support material: expanded clay and gravel. Two hydraulic retention times (HRT) of 24h and 18h were evaluated at steady-state c

8. Desenvolvimento de um sistema de recirculação com uso de wetlands construídas para efluentes da piscicultura / Development of a recirculating system using constructed wetlands for aquaculture effluents
Global aquaculture has been growing very fast in recent decades due to several factors, including: population growth, demand for low calorie protein and especially the reduction of natural fish stocks. Brazil has enormous potential to become a world leader in fisheries production in captivity. However, the development of aquaculture in Brazil must be conduct

9. Passagens / Passagens
Passages refers to transition, displacement, change, transmission and continuity. Perception of the body as a whole in the action of making; the movement and its resonances in connection with breathing and how this is transmitted in modeling the pieces. If passages here means relating differences, something that occurs somewhere between the being and the mat

10. Efeito da adição de argila expandida e adições minerais na formulação de concretos estruturais leves autoadensáveis
A busca por materiais alternativos de menor massa específica, redução na transferência de calor e propagação do barulho, associado à facilidade de manuseio e aplicação em estruturas de concreto armado, representa grande desafio na formulação e conhecimento do desempenho de concretos estruturais leves autoadensáveis, que tem tecnologia pouco difun

11. Start-up and steady-state conditions of an Anaerobic Hybrid Reactor (AHR) using mini-filters composed with two types of support medium operating under low loading rates
The present work aimed at studying the operational parameters of an Anaerobic Hybrid Reactor (AHR) removing organic matter of coffee wastewater with low concentration. The AHR was built similar to an UASB reactor, however the interior was filled with mini-filters composed by two types of support materials: expanded clay and rolled pebble. Three start-ups wer

12. Remoção de alquilbenzeno linear sulfonado (LAS) e caracterização microbiana em reator anaeróbio de leito fluidificado / Removal of linear alkylbenzene sulfonate (LAS) and microbial characterization in anaerobic fluidized bed reactor
Nesse trabalho foi estudado a degradação anaeróbia do alquilbenzeno linear sulfonado (LAS), um surfactante amplamente utilizado na fabricação de detergentes e presente em esgoto doméstico e águas residuárias industriais. Para isso foi utilizado reator anaeróbio de leito fluidificado em escala de bancada (1,2 L) preenchido com material suporte para i
