Structure and properties of ceramic brick colored by manganese-containing wastes

Abstract

The given paper investigates the influence of manganese-containing wastes on bulk coloring and physical and mechanical properties of wall ceramic materials with matrix structure. Conventional research methods to study physical and mechanical properties of ceramic specimens were used in the present study. The structure and phase state of decorative ceramic materials were investigated by means of physical-chemical analysis. Authors suggested the model to form coloring layer in ceramic matrix composites based on argillaceous raw materials and coloring pigment. Macrostructure was studied on ceramic samples manufactured according to the developed method from clay loam of moderate plasticity and wastes of manganese mining. The paper provides results of pilot testing on production of colored ceramic brick. It was found that incorporation of coloring component does not decrease strength properties of ceramic matrix materials. Authors defined the palette and color code for decorative ceramic specimens manufactured with different content of coloring component of manganese mining wastes according to RGB color codes chart.

Blocos Modulares Não Convencionais Com Subprodutos De Britagem: Influência De Pigmentos Inorgânicos

“…Na revisão bibliográfica realizada, nada mais se encontrou a respeito do uso de pigmentos coloridos em blocos modulares. Os trabalhos mais recentes encontrados são relativos à aplicação de pigmentos em tijolos cerâmicos queimados, como exemplos, citam-se Stolboushkin et al (2018) Tendo em vista a economia, a sustentabilidade e a preservação ambiental, os blocos modulares para alvenaria podem ser confeccionados com diversos subprodutos, dentre eles, aqueles advindos do processo da britagem de rochas e com vantagens técnicas em relação aos blocos modulares de solo cimento. O fato destes subprodutos não possuírem matéria orgânica, como a presente no solo, pode contribuir tanto no ganho de propriedades mecânicas, como na durabilidade.…”

The Effect of Manganese-Containing Pigment on the Strength of Ceramic Bricks

“…At the same time, the volume coloring of the product, especially in the case of obtaining saturated color tones, requires an increased consumption of coloring additives, which increases its cost. Reducing the cost of the product in this case is possible due to the use in the compositions of the masses of man-made wastes containing in enough quantity color-forming oxides necessary to give the material the desired color [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The choice of pigments is determined by the properties of the pigment and material, the nature of their interaction, as well as the processing parameters and operating conditions of the products.…”

Stochastic modeling of iron in coal seams using two-point and multiple-point geostatistics: A case study

“…However, iron elements can also help with gasification [7] and geophysical monitoring due to their magnetic properties [8]. Frequently, a high accumulation of iron or other metalliferous minerals in coal can change its usage from one of heat energy to other industrial uses, such as manufacturing ceramic walls and tiles [9,10]. Spatial modeling of iron grades is an essential component of coal resource estimation, which is used for downstream activities of coal mining projects, such as mine planning, coal preparation, and other analyses.…”
