Clay materials for ceramic tiles from the Sassuolo District (Northern Apennines, Italy). Geology, composition and echnological properties
Author(s) :
Dondi M.
Description :
In the Sassuolo area (northern Italy) there is the largest tilemaking district in the world, which has practically served over the past years as an industrial scale laboratory for assessing the technological properties of clays and their suitability for the production of wall and floor tiles. The lo...

Microstructure and mechanical properties of clay bricks: comparison between fast firing and traditional firing
Description :
Clay bricks fired using a traditional slow cycle and an innovative fast cycle were compared from the microstructural and mechanical viewpoints. Tests were performed on both a laboratory and a semi-industrial scale. For products with equivalent water absorption, fast firing leads to higher bend stren...

Effect of soda-lime glass on sintering and technological properties of porcelain stoneware tiles
Description :
The feasibility of waste glass recycling in ceramic tile production was assessed with special reference to fully vitrified products (porcelain stoneware). Soda-lime float or container glass was introduced, in replacement of sodic feldspar, in typical porcelain stoneware bodies (up to 10% wt) that un...

Zirconium titanate ceramic pigments: Crystal structure, optical spectroscopy and technological properties
Description :
Srilankite-type zirconium titanate, a promising structure for ceramic pigments, was synthesized at 1400 degrees C following three main doping strategies: (a) ZrTi(1-x)A(x)O(4), (b) ZrTi(1-x-y)A(x)B(y)O(4) and (c) Zr1-xCTiO4 where A = Co, Cr, Fe, Mn. Ni or V (chromophores), B = Sb or W (counterions) ...

The geology and mineralogy of a range of kaolins from the Santa Cruz and Chubut Provinces, Patagonia (Argentina)
Description :
In the Santa Cruz and Chubut provinces, Patagonia, Argentina, kaolin deposits were formed by "in situ" alteration of volcaniclastic rocks, such as the Bajo Grande, Chon Aike or Marifil Formations, or by erosion, transportation, and deposition of residual clays in small basins. This paper describes t...

Orimulsion fly ash in clay bricks. Part 1: composition and thermal behaviour of ash
Description :
A bitumen-in-water emulsion (Orimulsion) is currently used as a fuel in several thermal power plants worldwide. Orimulsion combustion produces a fly ash rich in S, Mg, V and Ni, which is processed to recover metals. In order to assess the feasibility of a recycling in clay brick production, a charac...

Orimulsion fly ash in clay bricks. Part 2: technological behaviour of clay/ash mixtures
Description :
In order to appraise the technological feasibility of the Orimulsion ash recycling in clay bricks, a laboratory simulation of the brickmaking process was carried out with various clay/ash mixtures up to 6% waste. Two different clays were selected and mixes were characterized by XRF, XRPD, TGA-DTA, T...

Orimulsion fly ash in clay bricks. Part 3: chemical stability of ash-bearing products
Description :
The chemical stability of clay bricks containing Orimulsion ash (up to 6 wt.%) was assessed with a laboratory simulation of the brickmaking process. The development of efflorescence, the amount of water soluble salts and their elution, the fraction of S, V, Ni, Mg, Ca, Na and K immobilized in the ce...

Water vapour permeability of clay bricks
Description :
The water vapour permeability of clay bricks has been experimentally measured in order to draw a representative outline of industrial products without pore-forming additives. The correlations between water vapour permeability and the main compositional and microstructural parameters of both bricks a...
