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...

Major deposits of brick clays in Italy. Part 1: Geology and composition. Part 2: Technological properties and uses
Description :
The Italian industry is the major European brick and roofing tile producer with about 16 million tons per year. To achieve this goal, a considerable spectrum of clay sources is under exploitation: from continental to ancient marine sediments. This overview deals with the major sources of brick clays...

Chemical, mineralogical and ceramic properties of kaolinitic materials from the Tresnuraghes mining district (Western Sardinia, Italy)
Description :
Kaolinitic materials crop out in the Tresnuraghes mining district (Western Sardinia, Italy). Three main kaolinitic deposits, located in the Patalza, Salamura and Su Fongarazzu areas, respectively, were investigated in order to assess their potential in the ceramic industry. The parent rock-types of ...

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...

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...

Description :
Low-cost zeolitic rocks are promising substitutes for feldspathic fluxes in ceramic bodies, since their fusibility, modest hardness and high cation exchange capacity (CEC) should improve grinding and sintering. Five large-scale Italian deposits of natural zeolites with different mineralogy were char...
