Description
Para um desenvolvimento sustentável no setor da construção civil é importante pensar à frente e trabalhar no aproveitamento de materiais de rejeição industrial como substitutos de agregados ou aglomerantes tanto em misturas de argamassas como de betão, como pensar em novas ideias.
Assim temos a indústria de papel e celulose, que por meio do processo Kraft processa a celulose e gera grandes quantidades de resíduos conhecidos como dregs e com a possibilidade de aproveitamento do resíduo que têm como destino final aterros, devemos procurar inovações tecnológicas construtivas, aliando-se ao desenvolvimento da construção sustentável, viabilidade económica e implementação de novos recursos.
Portanto para minimizar os impactos ambientais e atender às exigências económicas, estão a ser desenvolvidos estudos para avaliar a viabilidade do aproveitamento destes resíduos em produtos aplicados na construção civil. Dentro desse esforço, a presente dissertação tem como objetivo analisar os resultados de uma possível integração dos dregs na construção civil, através da incorporação deste material em tijolos produzidos através de uma mistura de solo-cimento. Assim a utilização de um tijolo sustentável composto por um agregado, por dregs e por cimento torna-se atrativo quer pelo seu processo de fabricação e quer por não ser necessário a queima do mesmo.
Não descurar que o objetivo principal foi analisar a mistura para o fabrico de tijolos de solo-cimento e não estudar uma argamassa, foram realizados ensaios para caracterizar o material envolvendo a análise de várias amostras da mistura de solo-cimento com adição de dregs. Foram fabricados provetes com uma mistura de referência e provetes com 15 e 30% de dregs por substituição do agregado, ambos os grupos de provetes foram ensaiados à compressão.
Após o ensaio à compressão chegou-se a resultados interessantes com a base de uma mistura de 30% de dregs, mas melhorados com a mistura de 15% de dregs, sendo a mistura de 15% de dregs escolhida para a continuação do estudo.
Já com o tijolo de solo-cimento e os ensaios aplicados a este, demostraram um bom potencial para a incorporação do resíduo, em quantidades adequadas na produção de tijolos de solo-cimento, reduzindo o custo da produção, além de diminuir os impactos ambientais com o destino atual do resíduo.
For sustainable development in the civil construction sector, it is important to think ahead and work on the use of industrial reject materials as substitutes for aggregates or binders in both mortar and concrete mixtures, as well as thinking about new ideas. So we have the pulp and paper industry, which through the Kraft process processes pulp and generates large amounts of waste known as dregs and with the possibility of using the waste that has landfills as its final destination, we must look for constructive technological innovations, combining the development of sustainable construction, economic viability and implementation of new resources. Therefore, in order to minimize environmental impacts and meet economic requirements, studies are being carried out to assess the feasibility of using these residues in products applied in civil construction. Within this effort, the present dissertation aims to analyse the results of a possible integration of dregs in civil construction, through the incorporation of this material in bricks produced through a soil-cement mixture. Thus, the use of a sustainable brick composed of an aggregate, dregs and cement becomes attractive both because of its manufacturing process and because it does not need to be burned. Not forgetting that the main objective was to analyse the mixture for the manufacture of soil-cement bricks and not to study a mortar, tests were carried out to characterize the material involving the analysis of several samples of the soil-cement mixture with the addition of dregs. Samples were manufactured with a reference mixture and samples with 15 and 30% of dregs by replacing the aggregate, both groups of samples were tested in compression. After the compression test, interesting results were obtained based on a mixture of 30% of dregs, but improved with the mixture of 15% of dregs, with the mixture of 15% of dregs being chosen for the continuation of the study. With the soil-cement brick and the tests applied to it, they showed a good potential for the incorporation of the residue, in adequate amounts in the production of soil-cement bricks, reducing the cost of production, in addition to reducing the environmental impacts with the current destination of the waste.
