This work has as its objective to evaluate the influence of a granite waste into a clayey ceramic body for obtaining of rustic wall tiles. As raw materials, a clayey ceramic body for red ceramic production and a granite waste, resulting from ornamental stones cutting with the multi-wire technology were used. Compositions using 0, 10, 20 and 30% of waste incorporated into ceramic body were prepared. Specimens were fabricated by uniaxial press-molding at 20 MPa and sintered at 1050°C. The following properties were determined: linear shrinkage, water absorption and flexural rupture strength. In general, within the error bar, there was no influence of the waste in the values of water absorption of the clayey ceramic body. The results showed that all investigated formulations used in this work for the production of rustic wall tiles attend the standards for water absorption and mechanical strength.

A ceramic body traditionally used to produce bricks and roofing tiles was reformulated by the addition of sand and illitic clay. The objective was to obtain a ceramic product with better technological properties. Specimens were made by uniaxial press-molding at 20 MPa and then fired at temperatures varying from 850 to 1100°C. The determined technological properties were: linear shrinkage, water absorption and flexural rupture strength. The results showed that both sand and illitic clay contribute to reduce the water absorption of the industrial clayey body. With respect to the flexural behavior, it was observed that the incorporation of sand decreased the mechanical strength. On the other hand, the illitic, incorporated in an amounts of 30 wt.% contributed to increase the mechanical strength of the clayey ceramic.

Residues incorporation into construction building materials is a promising sustainable alternative for the correct disposal of this kind of material. Brazil is one of the largest world producers of ornamental stones. Nevertheless, the disposal of these residues usually is made outside the industry, which contributes to environmental pollution. This work aimed to evaluate the incorporation of residues from the marble industry into ceramic bricks. Specimens of clay ceramic containing 10, 20, 30 and 40 wt.% of marble residue were prepared and fired at 900oC. The evaluation of the ceramic bricks added with marble residue was based on linear shrinkage, water absorption and mechanical resistance. These properties were compared with Brazilian standards. It was concluded that the incorporation of marble residues, with up to 20 wt%, into the ceramic body is technically feasible and positively influences the properties of the material.

Blast Furnace Sludge

The blast furnace sludge is a waste generated after the washing step of the blast furnace gas. The reuse of this waste in the steelmaking process itself is quite problematic. This study aims to analyze the possibility of the incorporation of a type of blast furnace sludge, benefited by a process that uses helical separators, into red ceramic. Specimens were prepared by uniaxial pressing at 20 MPa and then fired at 750°C and 950°C. The evaluated technological properties were linear shrinkage, water absorption and flexural rupture strength. The results showed that the benefited blast furnace sludge significantly influences the evaluated properties, by impairing the linear shrinkage and the water absorption but improving the mechanical strength.

In this study the objective was to evaluate the properties affected by the incorporation of phyllite and sand as raw materials in the composition of ceramic material for the roofing tiles production with light color using kaolinite clay from Campos dos Goytacazes – RJ, Brazil as main raw material. Specimens were prepared by uniaxial pressing at 20 MPa and fired at 950oC. The determined technological properties were: dry apparent density, linear shrinkage, water absorption and mechanical strength (three point bend test). The results indicated that the incorporation of sand and phyllite improved the dry apparent density, reduced loss on ignition and aluminum oxide content of the pure clay. These factors resulted in a reduced open porosity, improving water absorption and linear shrinkage. However, the mechanical strength was compromised due to the increase of quartz content.

The northern region of the state of Rio de Janeiro, Brazil, has a significant participation in the country ceramic production for civil construction owing to the abundance of raw materials, mainly kaolinitic clays. Each municipality in that region has ceramic industries using raw materials mined from its own deposits. Products such as bricks and tiles may lack the required quality due to the limited know-how on the applied raw material. The present work conducted a technological evaluation of the clayey raw material used in the municipality of São José de Ubá including its potential for ceramic processing at firing temperatures of 700, 850 and 950oC. The results indicated that only the ceramic fired at 950oC conforms to the specifications for water absorption and mechanical strength.

This work has as its objective to evaluate the effect in the physical and mechanical properties of a red ceramic by the incorporation of petroleum coke from a refining plant. The characterization of the coke was done by optical microscopy and DTA/TG. Compositions were prepared with 0, 1, 2 and 4 wt.% of petroleum coke incorporated into a kaolinitic clayey body. Rectangular specimens were formed by extrusion before firing at 950°C. The determined physical and mechanical properties were: flexural rupture strength and water absorption. The microstructure of the fired ceramics was evaluated by SEM. The results showed that the incorporation of up to 4 wt.% of petroleum coke is not deleterious to the water absorption and mechanical strength of the clayey ceramic fired at 950oC.

Brazil is currently one of the world leading producers and exporters of ornamental stones. The increasing production also generates a proportionally huge amount of wastes. Depending on stones such as granite, these wastes may be composed of relatively high content of alkaline oxides. This is a low melting point flux with advantage for a potential addition of the waste into common clay ceramic. Thus, the present work investigated the addition of a granite waste, generated during the sawing stage using the multi-wire technology, into clayey ceramics fired at 1200oC. This ceramic added with up to 30 wt% waste were evaluated in terms of linear shrinkage, water absorption and flexural strength. It was found that the waste fluxing compounds promoted a reduction in water absorption and increase in strength that are associated with an improved clayey ceramic.

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.
