Simple estimates of vehicle-induced resuspension rates
(Elsevier, 2011-10)
Road dust emissions are considered to be a major source of airborne particulate matter (PM). This is particularly true for industrial environments, where there are high resuspensionrates of deposited dust. The calculation ...
Electrokinetic and rheological properties of highly concentrated kaolin dispersions: Influence of particle volume fraction and dispersant concentration
(Elsevier, 2010)
An industrial kaolin was selected and characterised. Different dispersions were prepared with solids volume fractions between φ{symbol} = 0.20 and φ{symbol} = 0.47 in the presence of sodium silicate (between X<sub>s</sub> ...
Non-destructive measurement of bulk density distribution in large-sized ceramic tiles
(Elsevier, 2010)
An apparatus has been designed, built, and patented that is able, non-destructively, to determine bulk density distribution in large-sized ceramic tiles. The proposed method, based on the X-ray absorption technique, provides ...
Study of the rheological behaviour of monomodal quartz particle beds under stress: a model for the shear yield functions of powders
(Elsevier, 2011-09-15)
A model is proposed that describes the yield locus of powders. The model is based on the adhesive contact of elastic spheres theory developed by Johnson, Kendall, and Roberts (JKR model). The proposed model improves the ...
Hardness and Young's modulus distributions in atmospheric plasmas prayed WC–Co coatings using nanoindentation
(Elsevier, 2011-05-25)
A statistical indentation analysis of WC–Co coatings obtained by atmospheric plasma spray (APS) with two secondary plasma gases, H2 and He, was investigated using an instrumented indentation technique with the aim of ...
Influence of composition on mechanical behaviour of porcelain tile. Part III: Effect of the cooling rate of the firing cycle
(Elsevier, 2011)
This paper is the third part of a study focusing on determining the influence of the porcelain tile composition on mechanical behaviour of sintered bodies. Tile compositions were prepared according to a simplex-centroid ...
Calcium carbonate thermal decomposition in white-body wall tile during firing. II. Influence of body thickness and calcite content
(Elsevier, 2012-05)
The thermal decomposition process of the calcium carbonate (calcite powder) contained in porous ceramic pieces, with the same composition as that used industrially to manufacture white-firing wall tile bodies, was studied ...
Cleaner production of porcelain tile powders. Fired compact properties
(Elsevier, 2012-03)
A new ceramic powder preparation process, the droplet-powder granulation process (DPGP), was recently proposed for the cleaner production of ceramic tiles. The DPGP granules and resulting pressed compacts were characterized ...
A procedure to evaluate the resistance to biological colonization as a characteristic for product quality of ceramic roofing tiles
(Elsevier, 2011)
Ceramic roofing tiles suffer deterioration through time due to environmental exposure. Biological colonization affects the appearance and integrity of building materials, such as roofing tiles. The resistance to biocolonization ...
Lightweight Porcelain Stoneware by Engineered CeO2 Addition
(Wiley, 2010)
The use of porcelain stoneware in innovative applications such as the covering of internal walls or the manufacturing of ventilated facades may be limited by its relatively high density. In this paper, we discuss the ...
