Abstract

unidade de produção de cimento pozolânico de baixo impacto ambiental, obtido por resíduo misto de construção e demolição (rcd), e produtos resultantes para a construção civil, que combina estrategicamente operações de dosagem, mistura de britas graduadas de rcd e solo urbano, moagem, calcinação e adição de cal para formação de produto de baixo impacto ambiental, menos de 200 kg co2 / t produto, formado por cimento pozolânico (<150 <micrômetro>) misturado com britas de rcd com granulometria inferior a 50 mm. o invento trata de planta de reciclagem (figura 1), fixa ou móvel, de resíduos mistos de construção e demolição (rcd), que combina a britagem separada dos rcds de diferentes naturezas. resíduos cinza (com predominância de materiais cimenticios), vermelho (com predominância de cerâmica vermelha) e misto (composto pela mistura das duas classes anteriores) são estocados em silos de armazenagem da planta (dispositivos 1, 2, e 3, respectivamente). após a britagem (dispositivo 4), as britas graduadas (<50 mm) obtidas a partir de cada residuo são armazenadas em novos silos (dispositivos 6, 7, e 8, respectivamente), junto com resíduo de solo urbano (dispositivo 9) e de cal hidratada (dispositivo 14), podendo ser alimentados, em separado ou em conjunto, a depender do potencial para a produção do cimento a partir de finos de rcd misto. os finos dos rcd misto podem ser simplesmente dosados ou ativados termicamente, sendo, neste caso, necessário separá-los, a seco, por classificação pneumática, em aeroclassificador. dependendo do produto que se pretende produzir, os dispositivos da planta podem ser acionados ou não, e combinados de forma a obter o melhor resultado para cada produto planejado. em todos os casos, são obtidos cimentos pozolânicos de baixo impacto ambiental (< 200 kg de co2/tonelada de produto). a unidade gera produtos diferenciados pertencentes ao campo da construção civil com resistências à compressão inferiores a 25 mpa, como valas, pavimentos, argamassas, componentes cimenticios pré-fabricados e concretos, compatíveis com as exigências de resistência estabelecidas.low environmental impact pozzolanic cement production plant, obtained by mixed construction and demolition waste (rcd), and resulting construction products, which strategically combines dosing operations, mixing of rcd graded gravel and urban soil, grinding, calcination and lime addition for formation of low environmental impact product, less than 200 kg co2 / t product, formed by pozzolanic cement (<150 <micrometer>) mixed with rcd gravels with a particle size of less than 50 mm. The invention relates to a fixed or mobile recycling plant (Figure 1) of mixed construction and demolition waste (RCD), which combines separate crushing of different nature rcds. Gray (predominantly cementitious), red (predominantly red ceramic), and mixed (composed of a mixture of the above two) residues are stocked in plant storage silos (devices 1, 2, and 3, respectively). after crushing (device 4), graded gravels (<50 mm) obtained from each residue are stored in new silos (devices 6, 7, and 8, respectively), together with urban soil residue (device 9) and hydrated lime (device 14) and can be fed separately or together depending on the potential for cement production from mixed rcd fines. Mixed RCD fines can simply be metered or thermally activated, in which case it is necessary to dryly separate them by pneumatic classification into an aeroclassifier. Depending on the product to be produced, the plant devices can be triggered or not, and combined to obtain the best result for each planned product. in all cases low environmental impact pozzolanic cements (<200 kg CO2 / tonne of product) are obtained. The unit generates differentiated products in the field of construction with compressive strengths below 25 mpa, such as ditches, floors, mortars, prefabricated cementitious components and concrete, compatible with the established strength requirements.
