Aditivo surfactante de fonte renovável para redução do consumo energético na extrusão de massas de cerâmica vermelha

Abstract: Resumo O impacto de surfactantes na extrusão semiúmida de massas argilosas está diretamente relacionado ao desempenho associado à vazão mássica e respectivo consumo energético. Neste trabalho foi elaborada uma formulação baseada em uma massa empregada na fabricação de blocos estruturais aditivada com surfactante obtido de fonte renovável (tanino). O objetivo foi avaliar os impactos da adição do tanino na trabalhabilidade da massa, na redução do consumo de energia, na dureza do extrudado e nas propriedades dos … Show more

“…Academic research on the production of ceramic blocks for civil construction in terms of process improvement briefly follows two strands: the one that seeks to develop new ceramic materials, which have high thermal insulation and compressive strength, and another that seeks to optimize the manufacturing process for these materials. In the literature there is an effort both to obtain the mineralogical composition of clays and to understand how it influences the properties of ceramic materials [2], and to develop new materials for the manufacture of ceramic blocks, such as the insertion of surfactant [3] or fly ash [4] in the clay or to increase the mechanical strength after drying and firing.…”
