“…The clay was obtained from the Sardinha ceramic industry in Campos dos Goytacazes. Similar clays were investigated in recent works [12][13][14][15][16][17][18][19], in which their physical and chemical characteristics were presented. In short, the main clay mineral is kaolinite.…”

The kaolinitic clays from Campos dos Goytacazes, state of Rio de Janeiro, Brazil, are known by their high plasticity and refractory behavior that require sintering at elevated temperatures for consolidated ceramic structures. Processing temperatures below 1000°C may also be used if the clay body contains fluxing compounds that promote lower temperature molten phases and reduce porosity. Commercial fluxes are relatively expensive but some wastes, such as those generated in industrial activities related to glass fabrication, could provide inexpensive fluxing agents. In the present work, the incorporation of up to 40 wt% of a sludge waste from the polishing stage of glass production into a Campos dos Goytacazes clay body fired at 900°C was investigated. It was found that the sludge incorporation improved both the ceramic water absorption and the mechanical strength.

“…In some cases, the clay is mixed with additives -for example, large pieces sometimes contain 10-20% grog (crushed and powdered red pottery), which adds stiffness and reduces shrinkage when red (e.g. Candido et al, 2014). At this point, the slip has the consistency of syrup or motor oil.…”

Clay used in the manufacture of the artisanal drinking water vessels known as Labu Sayong has been found to contain fine volcanic ash from the Young Toba Tuff (YTT) eruption. Thick distal YTT ash deposits have been found in the Lenggong-Kuala Kangsar area. Reworking, transportation and redeposition of the ash has caused it to be mixed with alluvial clay, silt and sand. The material used in the manufacture of Labu Sayong is coarse compared to that used in the manufacture of other ceramics, since the vessels must be slightly porous and permeable to water for the purpose of evaporative cooling. In actual use the vessel comes with a supporting dish which catches condensation and seepage. However, the dish lacks strength to support the weight of the water stored in the vessels. This study evaluates the effect of the addition of three substances - rice husk, grog and pure volcanic ash into the natural clay. Even though the addition of grog and volcanic ash does not affect the shrinkage during dehydroxilation, shrinking starts to happen at a lower temperature with the ash. Large amount of organic material is burned with the rice husk leading to very porous materials. Volcanic ash is found to be a favourable additive to add to the vessel strength without compromising on the porosity.

“…Whereas, high porosity and microstructural defects in natural ornamental stones lead to contamination and brittleness, since outside fluids can penetrate to natural stone through pores and propagate cracks. Despite abovementioned positive points of artificial stones, it should be noted that some of them are not resistant enough in high traffic areas, as the materials are vulnerable to abrasion [11,30,31].…”

In this study, waste silica from Alborz silica mineral processing factory was recycled as raw material for the production of a novel artificial stone to be used in civil construction. The size of the waste materials of this plant is less than 100 microns. Waste silica powder was mixed with unsaturated polymer resins as a binder. Under pressure, vibration and vacuum conditions, artificial stone with high compressive strength of 100 MPa, the tensile strength of 37 MPa and flexural strength of 98 MPa was produced within 15 min. Furthermore, in all of the produced artificial stones, due to the usage of resin, the flexural strength is higher than the tensile strength whereas, in natural stones, tensile strength is more than flexural strength. Moreover, using bentonite made a positive effect on the strength and quality of the stone, whereas kaolin declined the quality and the resistance of the artificial stone. Besides, the produced artificial stone has a lower specific gravity (2.14 g/cm 3) and water absorption (0.06 g) than natural stone, which is one of the most prominent advantages of artificial stone. What's more, low corrosion and were obtained against diluted sulfuric acid (0.0097 g) and hydrochloric acid (0.0313 g). Besides, due to the presence of impurities in the waste materials of Alborz silica factory, the produced artificial stones are brown. To reach the desired color, there are several metal oxides which could be added to the combination.
