Revêtements en phase aqueuse -- Séchage:Peinture en phase aqueuse -- SéchageIndex. décimale : 667.9 Revêtements et enduits Résumé : Corrosion of steel rebars in reinforced concrete is one of the major problems in the construction industry. Carbonation reactions of concrete with carbon dioxide and, mainly, the chloride salts action are the main causes responsible for concrete degradation. Protective coatings help to improve the durability of concrete structures by acting as a physical barrier against the corrosion agents. Waterborne paints are usually used for concrete protection rather than solvent-based paints since they are less pollutant. The aim of this work is to investigate the influence of the pore size and porosity on the permeability of the paints films toward sodium chloride. Three characterization methods from membrane science were implemented to characterize paint coatings. The time-lag method was used to determine the permeability toward the sodium chloride and toward helium and argon, these for approximately 100% relative humidity. From the seven waterborne paints formulated, only one was found to be suitable for surface protection of reinforced concrete, since its permeability toward NaCl was smaller than 10−14 m2 s−1, the threshold value required by National Laboratory of Civil Engineering (LNEC) in Portugal. For the formulated paints, it was observed that the average pore size correlates well with the permeability toward sodium chloride. This is an important result since obtaining the permeability toward sodium chloride of corrosion protective paints is very time consuming, while the average pore size can be obtained in a much shorter time.

XénonIndex. décimale : 667.9 Revêtements et enduits Résumé : The cure rate of a high gloss overprint varnish was compared using a standard medium pressure mercury lamp and a high intensity xenon chloride lamp. Samples with equal photoinitiator concentration cured at a much faster rate using the xenon chloride lamp. It was found that the concentration of the photoinitiator could be greatly reduced and still give rapid rates of curing when the xenon chloride lamp with peak output at 308 nm was used.

Tannage Résumé : Total nitrogen (TN) in tannery wastewater is difficult to remove completely, because the low C/N ratio of the wastewater leads to inadequate denitrification. Sodium acetate was used as an extra carbon source to improve the denitrification efficiency and the TN removal. The appropriate COD/TN ratio for denitrification using sodium acetate was 5.1, at which the TN concentration of tannery wastewater decreased by 95%. A much faster removal of TN was obtained by adding sodium acetate in denitrification than by adding common glucose. These results showed that sodium acetate was a high-quality carbon source for a complete and rapid denitrification of tannery wastewater. The denitrification efficiency decreased with decreasing temperature and increasing chloride concentration. However, when the carbon source was made sufficient by adding sodium acetate, complete denitrification was stil) obtained even at 15°C or 10000mg/L of chloride concentration.

Titre : Evaluation of surface preparation methods to remediate chlorides on bridges Type de document : texte imprimé Année de publication : 2017 Article en page(s) : p. 28- Langues : Américain (ame) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.
