“…Consequently, the MOR became lower as the RSA content in the mixtures increased; however, the MOR values of all mixtures lay above the minimum value laid down in ISO standard 13006 ( 35 MPa) for the classification of Group BI a dry-pressed ceramic tiles with low water absorption [1]. The variation of E in the fired test pieces indicates the general behaviour of the materials, showing that as total porosity increased, E decreased (see Figures 4d and 10b), corroborating the findings of many authors regarding different ceramic materials who have reported the zero contribution of the pore phase to the overall Young's modulus of the ceramic body considered as a multiphase material [63][64][65][66]. Although E decreased with increasing RSA contents in the mixtures, the values of E in most mixtures were within the range of values reported by other authors (50-72 GPa) [66,67].…”

This study examines the effects of replacing fluxing and filler materials with rice straw ash (RSA) in manufacturing porcelain stoneware tile, using the design of experiments (DOE) methodology. The results of the characterization were used to obtain statistically significant, valid regression equations, relating the technological properties of the dried and fired test pieces to the raw materials content in the unfired mixtures. The regression models were analysed in relation to the X-ray diffraction and scanning electron microscopy results and used to determine the most appropriate combinations of traditional raw materials and RSA to produce porcelain stoneware tiles with specific technological properties. The studied range of tile body compositions: clay (40 wt%), feldspar (20-50 wt%), feldspathic sand (5-20 wt%), and RSA (0-25 wt%) was shown to be appropriate for porcelain stoneware tile manufacture.

“…This result contradicts the prestressed theory, which proposes that quartz particles produce strong compressive stresses on the glassy phase with consequent mechanical property enhancement. In a recent study, De Noni et al 5 have found that quartz particles have a decisive contribution on increasing the fracture energy in porcelain tile, either by increasing the state of compressive residual stress in the glass matrix, or by promoting a combination of the mechanism of crack deflection and microcracking. However, the results are in good agreement with the results given by Maity and Sarkar 25 , which show that quartz particles have an adverse effect on the flexural strength of porcelain compositions.…”

This work examines the effect of microstructure (aspect ratio of mullite crystals and proportion of crystalline and amorphous phases) as well as different physical features (bulk density, closed and open porosity and absolute density) on the mechanical properties of a standard porcelain stoneware composition (50% kaolinitic clay, 40% feldspar and 10% quartz) fired in the 1200-1300 • C temperature interval using a fast firing schedule. The mechanical behaviour was evaluated in terms of bending strength, Vickers microhardness, fracture toughness and Young's modulus. After viewing the results, it can be concluded that increased σ f , H v and E values were mainly due to open porosity, percentage of mullite phase and morphology of secondary mullite needles, whereas closed porosity and quartz particles have no influence on these properties.

“…Several researchers have not found a clear relationship between mullite content and bending strength (72,73,74). De Noni et al (84) in a study on the influence of composition on mechanical behaviour of porcelain tile showed that mullite significantly worsen the fracture energy, which invalidates the mullite hypothesis as a mechanism to strengthen the porcelain tile.…”

Porcelain stoneware is a strongly sintered ceramic material fabricated from ball clays-quartzfeldspar mixtures. Porcelain stoneware is characterized by its excellent technical and functional properties (low water absorption, high mechanical properties, resistant to chemical substances and cleaning agents, aesthetic possibilities …). These characteristic and technical features make that among the different types of ceramic tile, porcelain stoneware is the ceramic product that in the last years has best withstood the economic crisis in the construction sector. These properties are related to the microstructure of porcelain stoneware, which is a grain and bond type with large particles of filler (quartz), mullite crystals, a silica-rich amorphous phase and porosity. The understanding of the relationship between the microstructure and the properties of porcelain stoneware is hardly important for the development and design of these materials whose tendency is the manufacture of thinner tiles with higher dimensions but must continue to comply the specific technical requirements. RESUMEN:Relación entre la microestructura y las propiedades tecnológicas en gres porcelánico. Revisión bibliográfica. El gres porcelánico es un material sinterizado fabricado a partir de una mezcla de arcillas, cuarzo y feldespato. Tecnológicamente, el gres porcelánico se caracteriza por sus excelentes características técnicas y funcionales (baja absorción de agua, buenas propiedades mecánicas, resistente a substancias químicas, posibilidades estéticas…). Estas cualidades han propiciado que, entre los diferentes tipos de baldosa cerámica, es el gres porcelánico el producto que mejor ha resistido la crisis económica sufrida por el Sector de la Construcción. Las propiedades tecnológicas están relacionadas con su microestructura, compuesta de partículas de cuarzo, cristales de mullita, fase amorfa y porosidad. El conocimiento de la relación entre la microestructura y las propiedades tecnológicas del gres porcelánico es de gran importancia para avanzar en el diseño y desarrollo de estos materiales, cuya tendencia es la fabricación de piezas de mayor formato y menor espesor pero que deben seguir cumpliendo con los requerimientos especificados para su aplicación.
