The red mud is a well known insoluble residue generated in the Bayer process to benefit bauxite ores. This residue is composed of ceramic related compounds such as iron oxide, sodium aluminum silicates, carbonates, calcium aluminates and titanium dioxide. The incorporation of industrial residues in clay ceramics has been extensively investigated, not only as an environmentally correct solution but also as an economic way to save raw materials. Therefore, the present work evaluated the properties of clay ceramics incorporated with up to 40 wt% of red mud. Clay bodies with different percentages of red mud were press-molded and fired at 750, 950 and 1050°C. The evaluated technological properties were linear shrinkage, water absorption and mechanical strength. Sensible changes in such properties were found with red mud addition. In particular, the ceramic fired at 1050°C displayed favorable water absorption with red mud incorporation.

This study focuses on the identification of an appropriate composition of raw materials for ceramic products from commonly available red clays in Sri Lanka. The raw materials were characterized in terms of particle size distribution, chemical and mineralogical composition. Different formulations of samples were prepared, and the linear shrinkage, water absorption and flexural strength of the final products were measured. Microstructures of fired samples were observed under a scanning electron microscope. The best quality product was obtained when the sample contains a high amount of illite clay in a mixture of 80 wt.% clay-silt and 20 wt.% sand. The presence of higher concentrations of the metal oxides Na2O, K2O and Fe2O3 (total ~21 wt.%) in the clay-silt fraction of samples has resulted in obtaining higher technological properties of the body. The flexural strength and the water absorption of the product are 26.82 MPa and 6.51% respectively. If the raw materials contain lower amounts of the oxides Na2O, K2O and Fe2O3, higher amounts of clay-silt fraction (up to 90 wt.%) must be added to obtain an optimum quality product.

The microstructural and technological properties of clay ceramic incorporated with 10 and 20 wt% of elephant grass ashes were investigated at different firing temperatures of 650, 850 and 1050oC. X-ray diffraction were used to obtain the minerals and phase compositions. The microstructure was analyzed by scanning electron microscopy. The technical properties related to water absorption, linear shrinkage and flexural rupture strength were obtained by standard test. The results showed significant changes in the microstructure and phasic composition with increasing firing temperature. A marked improvement in the water absorption, decreasing to 18% as well as increase in strength, above 5 MPa, was found at 1050°C. However, only a slight contribution might be attributed to the incorporation of elephant grass ash. Nevertheless, its use as a by-product and the associated saving in clay are relevant environmental and economical advantages.

The addition of industrial residues into common red clay ceramic has been, from many decades, an alternative of using other low cost raw materials and, more recently, as an environmentally correct destination for polluting substances. An important residue, known as yellow sludge, is that generated at the water clearing stage (WCS) of a treatment plant by some heavy industries such as an integrated steel making. Since this yellow sludge residue is normally disposed in ways that pollutes water bodies, the objective of the present work was to characterize a WCS yellow sludge and investigate its addition into clay ceramics. The residue was characterized by X-ray fluorescence, particle size distribution and scanning electron microscopy. The addition was carried out up to 7.5 wt% followed by firing at 800oC. The added ceramics were evaluated in terms of water absorption, linear shrinkage, dry apparent density and flexural rupture strength. It was found that the residue addition does not practically alter the ceramic technical properties.

TheNossa Senhora do Carmomining company, located at the southern of Santa Catarina (SC), Brazil, explores a large amount of feldspar to the ceramic market. As a result, waste is inevitable in the production and processing of the feldspar mineral, which results in an environmental impact. Therefore, this study aims to evaluate the effect of the addition of the waste coming from the feldspar mining in the composition of ceramic bricks. In this way, the waste and a clay mineral were characterized. The waste (0, 5, 15 and 25 wt%) was added to a composition of clay brick based on a standard clay fromMorro da Fumaça, Santa Catarina, Brazil. Specimens were extruded and sintered at temperatures of 1123, 1223, and 1323 K. The technological properties assessed in this study were linear shrinkage, water absorption and bending strength. The data were assessed by analysis of variance. The results showed the feasibility of adding 15 and 25 wt% of waste to the brick composition. All technological properties were improved when compared to pure samples, except for linear shrinkage. The analysis of variance showed significant and reproducible effects for the water absorption results. The results for linear shrinkage and bending strength showed no statistical significance.

The cost of producing sanitary ware in Bangladesh is substantially low as compared to the advanced countries, because of low labour cost and abundance of basic raw materials. Ten sanitary ware compositions were prepared using Bijoypur clay, black clay, red clay, ball clay and china clay with fluxes and filler materials. Chemical compositions of the raw materials and the formulated batch compositions were determined. Physical properties (linear shrinkage, bulk density, apparent porosity, water absorption etc) and the modulus of rupture (MOR) of the prepared body compositions were also determined. The sample specimens were fired at 1150°C and 1200°C. Compositions S-3, S-4, S- 5, S-7, S-8 and S-10 at 1150°C were found to be of good quality. Key words: Linear shrinkage; Bulk density; Water absorption; MOR; Red clay; Black clay. DOI: 10.3329/bjsir.v45i4.7386 Bangladesh J. Sci. Ind. Res. 45(4), 387-392, 2010

Abstract This paper reports the development and characterization of some new ceramic materials from hazardous bauxite red mud (50 to 100 wt.%) and blast furnace slag (10 and 50%). This research aimed to demonstrate the possibility of expanding the raw material base for ceramics production, completely replacing the traditional natural raw materials (clay and sand) by hazardous industrial wastes composites with increasing local and global sustainability. Studies on the physicochemical processes of the ceramic structure’s formation were conducted by the XRF, XRD, AAS, SEM with EDS, and LAMMA methods. Changes in flexural strength, linear shrinkage, water absorption, and density were determined during the sintering process at 1000°, 1050°, 1100°, 1150°, 1200°, and 1225°C. The ceramics` flexural strength after sintering at 1225°C reached 19.78 MPa due to the syntheses of the mainly glass-like structure formation, confirmed by SEM, EDS and isotopes LAMMA methods with the complete binding of the heavy metals.
