Coatings are used in a variety of applications. Last decades more and more coating systems are transforming from solvent to waterborne coating systems. In this study the influence of pigments on the water permeability of a waterborne coating system is studied, with special interest in the possible interfacial layer of additives around the...

This paper presents the characterisation of a selection of NHL-based commercial products for the conservation of historic masonries. Two binders and four ready-mixed mortars have been analysed; both the anhydrous raw materials and the hardened mortars have been studied, focusing on those parameters which can be used as selection criteria. The...

This paper investigates the economic effects of full corrosion surveys of concrete structures. The background is that the existing concrete infrastructure is aging, while being exposed to aggressive influences, which increases the occurrence of corrosion and related concrete damage over time. The central proposition is that solely relying on...

Injection of chemicals in masonry walls is a commonly used technique for tackling rising damp. The presence of a high moisture content in the wall to be injected may sometimes limit the effectiveness of the intervention. This paper reports an experimental study of curing time, spreading and effectiveness of 15 injection products in bricks with...

Abstract Granulites constitute a major part of the (lower) continental crust, occurring on a regional scale in many metamorphic belts. Their origin is generally discussed in terms of vapour-absent melting and fluid-assisted dehydration. This last model is notably supported by the occurrence of two immiscible free fluids at peak- and retrograde...

Cathodic Protection (CP) of steel in concrete has been used over the past decades in order to increase the remaining service life of concrete infrastructure. CP involves the application of an electrical current to the corroding reinforcing bars, thus stopping and preventing further corrosion. The application of current on the reinforcing steel...

The problem of deterioration of historical building materials, namely stone, wood and glass has become more and more urgent. Climate changes have increased the impact of natural decay whilst socio-economic requirements claim a more sustainable use of existing built heritage. The EU project NANOMATCH addresses this problem through the development...

OnEouten door het gebruik van kompressen is een techniek die meer en meer gebruiK wordt in de conservering van historisch metselwerk. Niettemin, wordt ontzouten nog vaak uitgevoerd op een trial and error basis, zonder wetenschappelijke kennis van de processen die vocht- en zouttranspoft regelen. Om het ontzoutingsproces te optimaliseren is,...

Alkali-silica reaction (ASR) is a deleterious mechanism known to affect several concrete structures worldwide. During this process, alkali ions present in the pore solution react with reactive components of the aggregate particle and, as a result a hygroscopic gel is formed. The produced gel absorbs water from the surrounding cement paste and...

Two modified hydrotalcites (MHTs) intercalated with nitrate and aminoben-zonate anions, (i.e., CaAl-MHT-NO3 and CaAl-MHT-pAB) have been synthesized. The intercalation of CaAl-MHT-pAB was achieved by anion exchange of nitrate in the host material, CaAl-MHT-NO3, which was prepared by a coprecipitation method. Materials characterization was...

Corrosion of reinforcing steel in concrete structures causes concrete cracking and steel diameter reduction, eventually resulting in loss of safety. Conventional repair means heavy, labour intensive and costly work and the required quality level is under economic pressure. Consequently, conventional repair is short lived in many cases. An...
