“…The slit sludge contained roughly 48% clayey particle sizes and 18% sand in addition to the slit size particles. 30 As clay derives its plasticity property from the large surface areas of their minute (<2 µm) particle sizes, 31 the high mass fractions of the fine powdered of the clay and sludge materials could support the incorporation of nonplastic materials such as WMH for brick manufacture. According to Mbumbia et al, 32 these fine particles are preferred for improved stabilization of bricks by firing since their increased specific contact surfaces facilitate fusion bonding at elevated firing temperatures.…”

The consumption of colossal quantities of materials in the building industry has advanced the swift depletion of clean clay reserves. The use of organic additives in brick production is conserving clay resources. In addition, in some cases, it can lead to improvements in some material properties, such as decreasing thermal conductivity and increasing the capacity of the ceramic material in terms of thermal insulation. In the present investigation, waste millet husk (WMH) was incorporated in different proportions to clays to ascertain its influence on the fired brick properties. The raw materials were characterized for their physical, chemical, and thermal properties and found suitable for use in fired brick production. Additionally, the prepared modeled brick samples were tested for their physico-mechanical properties. The results indicated that linear shrinkage and weight loss increased, whereas bulk density decreased from 2.06 to 1.58 g/cm 3 depending on WMH incorporation amount in the clays and firing temperature. Similarly, compressive strength reduced by up to 68%. Thermal conductivity beneficially reduced by 42% with the addition of 16 wt.% of WMH. The best results in terms of mechanical properties were obtained with 4 wt.% of the WMH. In terms of thermal insulation, the best results were exhibited in the samples admixed with 16 wt.% of WMH. The results showed that porosity and bulk density were critical determining factors that directly influence the bricks physico-mechanical properties.

“…A Figura 9 apresenta as micrografias obtidas por MEV das regiões de fraturas das cerâmicas queimadas a 950ºC. Segundo VIEIRA e MONTEIRO [15] as cerâmicas vermelhas queimadas em temperaturas inferiores a 970ºC não apresentam uma consolidação estrutural eficiente apresentando assim regiões de porosidade e rugosidade, por isso ficou perceptível que as composições apresentaram uma microestrutura semelhante, com regiões de falhas e morfologia grosseira associada a partículas rugosas e poucas áreas lisas.…”

Resumo Este trabalho tem como objetivo caracterizar e estudar o comportamento tecnológico de dois tipos de argilas oriundas do município de São Miguel do Guamá a partir de formulação argilosa. Foram testadas formulações compostas pela mistura e não mistura de argila forte e fraca. As matérias-primas foram submetidas as análises de DRX, FRX, MO, MEV. Os corpos de prova foram prensados uniaxialmente em matriz retangular metálica. As propriedades físicas e tecnológicas determinadas foram: Porosidade aparente, massa específica aparente, absorção de água, retração linear de queima e resistência à flexão em três pontos. A microestrutura das cerâmicas foi avaliada por MO, MEV. Os resultados indicaram que as argilas possuem características favoráveis para produção de blocos de vedação, porém a maior resistência do material ficou com a mistura de 50% de argila fraca mais 50% de argila forte. Palavras-chave:Bloco de vedação; Argila; Cerâmica vermelha, São Miguel do Guamá.
