1. Considerations on design and implementation parameters of domestic wastewater treatment by subsurface flow constructed wetlands
RESUMO As wetlands construídas podem ser uma alternativa para comunidades afastadas de centros urbanos que não são atendidas por rede de tratamento de esgoto. Visando à orientação para implantação do sistema de wetlands construídas de fluxo subsuperficial, foi levantada uma série de informações a respeito dos aspectos construtivos, das plantas e

2. Análise das propriedades físicas e mecânicas de blocos de concreto prensados sem função estrutural com incorporação de PET reciclado
RESUMO O presente trabalho apresenta a análise de um elemento não convencional para sistema vedação de edificações: o bloco de concreto prensado com a incorporação de PET reciclado. Para tanto foi realizada uma análise experimental realizando-se a substituição, em volume, do agregado miúdo (pó de pedra) por PET triturado, nos teores de 15%, 30%

3. Mechanical behaviour of steel fiber reinforced concrete with stone powder
ABSTRACT Nowadays, there is an increasing interest in the development of eco-friendly materials. Thus, environmental challenges due to the necessity of reducing worldwide levels of CO2 emissions, to limit the energy consumption and to use industrial waste are promoting an increasing effort to find viable alternatives to minimize pollution from the main produ

4. Influence of Compaction Pressure and Particle Content on Thermal and Mechanical Behavior of Artificial Marbles with Marble Waste and Unsaturated Polyester
Compact artificial stones are widely used in buildings around the world, and the expected demand to the next years is increasing. In this study, stone fragments from marble processing are recycled as raw materials for produce compact artificial stones using compaction in a vacuum environment (100 mm Hg). Crushed marble waste (80 and 85%wt) are mixed with uns

5. Experimental investigations on mode II fracture of concrete with crushed granite stone fine aggregate replacing sand
With a view to implement sustainability concepts (namely, use of locally available materials and industrial by-products) in the concrete construction industry, the possibility of use of crushed stone fine aggregate as replacement to river sand is explored in this paper. Towards this, tests have been carried out on concrete cubes and concrete cylinders. The e

6. Método de dosagem de concreto pelo volume de pasta com emprego de cinza volante / Concrete mix-proportioning method by cement paste volume using fly ash
This study was developed in order to create and a streamlined methodology of concrete mix proportioning using fly ash to reduce the cement content and an intensive use of a pollutant contributing to the increase of sustainability in construction through reducing consumption of clínquer and the release of carbono dioxide to the atmosphere. It was established

7. Alternativas para o transporte da areia e brita. / Alternatives for sand and crushed stone transportation.
This work aims at focusing the possibility of cost reduction by the utilization of alternative means of transportation in relation to highways, railways and waterways in order to obtain sand and gravel, which are highly consumed, for civil construction at low added value to be available in São Paulo city. The mining activities as well as the other economic

9. Aproveitamento de filer de pedreiras da região metropolitana de Goiânia em pavimentos flexíveis urbanos [manuscrito]: avaliação técnica e sócio-ambiental / Use of filer of quarries in the metropolitan area of Goiania flexible pavements in urban [manuscript]: assessment technical and socio-environmental / Use of filer of quarries in the metropolitan area of Goiania flexible pavements in urban [manuscript]: assessment technical and socio-environmental / Aproveitamento de filer de pedreiras da região metropolitana de Goiânia em pavimentos flexíveis urbanos [manuscrito]: avaliação técnica e sócio-ambiental
The generation of industrial waste has been the object of increasing attention in the field of Science and Technology because of the problems which arise when it is stored and inadequately disposed of. This can have negative consequences for the worker, the company and for the neighboring population. In addition it can generate liabilities for the environmen

11. Contribution to Crushed Stone Petrography / Contribuição à petrografia de pedra britada
It is extremely important to know the physical and chemical properties of aggregate mineralogical composition so that the construction where they will be used is not compromised. In this sense, knowing the petrography and mineralogy is as necessary as knowing the geology of the rock deposit to be developed as a source of crushed stone. The main purpose of th

12. Estudo de características mecânicas do concreto compactado com rolo com agregados reciclados de construção e de demolição para pavimentação. / Study of mechanical characteristics for roller compacted concrete using waste aggregates from civil construction for paving.
This thesis work seeks the study of rolled compacted concrete (RCC) mixtures employing recycled waste aggregate from civil construction and demolitions as alternative for asphalt or concrete pavement bases, comparing some mechanical and physical characteristics to traditional virgin stone aggregate RCC. It is usual the use of recycled waste aggregate in Euro
