Electricity generation at Mae Moh Power Plant in Lampang, Thailand, uses lignite as fuel. The output is 3.0 to 3.5 million tons of fly ash per year and 1.5 to 2.0 million tons of bottom ash per year. Fly ash is widely used in concrete application but for bottom ash, it is not very useful. When considering the phase of bottom ash containing quartz, anorthite and hematite, it was found that there are suitable chemical compositions for replacement of raw materials in ceramic tile. Generally, the stoneware tiles are composed of quartz, mullite, feldspar, and glass phase. Water absorption of stoneware ceramic tiles is below 5%, high strength, fire resistance, and low warpage. Firing or sintering at rather high temperature as 1000-1250 °C is the manufacturing process for this type of tile. The changes in crystal structure and glassy phase formation in tile texture during sintering will be often result the tile to warpage or bent. The more or less lean depends on the viscosity of the glassy phase that occurs at high temperatures in the tile if less viscosity will cause higher warping rate that effect on the shape, and quality of the workpiece. The research has reported that anorthite phase improves the viscosity of a liquid phase or glassy phase when the tile is sintering at high temperatures and lead to high density and low water absorption. This research is interested in studying the effect of using lignite bottom ash as an ingredient in ceramic tile texture to produce low water absorption type by analyzing the effect of percentage of lignite bottom ash to warpage and important properties of ceramic tiles.

Sugarcane Industry

The sugarcane industry generates huge amounts of sugarcane bagasse ashes (SCBA). This work investigates the incorporation of a SCBA waste as an alternative raw material into a clay body, replacing natural clay material by up to 20 wt.%. Clay ceramic pieces were produced by uniaxial pressing and fired at temperatures varying from 700 to 1100 ºC. The technological properties of the clay ceramic pieces (linear shrinkage, apparent density, water absorption, and tensile strength) as function of the firing temperature and waste addition are investigated. The phase evolution during firing was followed by X-ray diffraction. The results showed that the SCBA waste could be incorporated into red ceramics (bricks and roofing tiles) in partial replacement for natural clay material. These results confirm the feasibility of valorisation of SCBA waste to produce red ceramic. This use of SCBA can also contribute greatly to reducing the environmental problems of the sugarcane industry, and also save the sources of natural raw materials used in the ceramic industry.

The incorporation of a granite waste into a vitrified ceramic tile body was investigated. The granite waste came from an industry of stone sawing operations located in the municipal area of Santo Antônio de Pádua, State of Rio de Janeiro, Brazil. The investigated compositions were elaborated substituting partially and totally the feldspar by the granite waste. Cylindrical specimen were prepared by uniaxial pressure at 30 MPa and then fired at temperatures varying from 1050 to 1200oC. Fired properties such as bulk density, linear shrinkage, water absorption and diametrical compression were determined. The microstructure of fired samples was evaluated by scanning electron microscopy. The results showed that the replacement of feldspar by granite waste promoted a better vitrification, decreasing the open porosity and increasing the mechanical strength.

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.

In the south of Ceará (Brazil), Cariri region, there is a production center for roof tiles and bricks. At that same region, there has been an expressive mining of laminated limestone, known as Pedra Cariri (Cariri Stone), which has produced large amounts of CaCO3-rich waste, that causes undesirable impacts to the environment. This work aimed to analyze the feasibility of producing rustic ceramic tiles, made up of clayey masses used in the region with the addition of this waste, aiming at the diversification of red ceramic products in a sustainable way. The mixtures were pressed, fired in maximum firing temperature which varies from 750° to 1150oC and had their physical-mechanical characteristics tested. The results indicated that the clayey mass is composed of kaolinite, feldspar and quartz, while montmorillonite and/or vermiculite is only found in roof tile clayey mass. The waste is mainly made of calcite. In general, the values of water absorption were compatible with porous rustic ceramic tile and the addition of Pedra Cariri waste provided lower values of firing shrinkage as well as the increase of the flexural strength. The samples of roof tile clayey mass (10% of waste at 850°C and at 1150°C) obtained physical-mechanical property values that match Brazilian technical norms to BIII type ceramic tile. Therefore, the mixture formulated with tile clayey mass and limestone waste presents potential to be utilized in the manufacture of ceramic roof tiles.
