San Jerónimo Monastery (Granada, Spain) was selected as a case study for the investigation of the effect of indoor environmental conditions on salt weathering and for on-site testing of a remediation treatment using crystallization inhibitors on account of the extreme salt damage affecting both the building stone, a biomicritic limestone,...

Er zijn momenteel heel veel ontwikkelingen gaande in het materialenveld voor de bouw: materialen met lage energy footprint, materialen van biologische oorsprong, responsieve materialen, materialen met additionele functionaliteit en al deze nieuwe materialen komen elder in deze editie aan de orde. Naast deze zichtbare en in de nog te bouwen...

ABSTRACT: The conservation of historic concrete is an increasing task, challenging both concrete repair specialists and conservation specialists. In practice, too often repair strategies are followed where conserva-tion strategies would have been necessary. The application of repair techniques poses two threats towards the historic concrete:...

De leer de staalconstructies brengt meesters voort. En leermeestrers brengen opvolgers voort. Wetenschappelijk onderzoek, kennisontwikkeling en -overdracht is van meet af een zaak van groot belang binnen de vereniging Bouwen met Staal. En daarmee ook het pact met haar beoefenaars. We bevragen zeven leermeesters naar de kiem en de vrucht van hun...

Water uptake by multilayer films plays an important role in their performance. Individual layers may consist of different polymeric phases. Understanding the water uptake in such systems requires knowledge of the water distribution, its state in the polymer, and influence on the polymeric phases. This study illustrates the application of high...

Tegenwoordig kunnen betonconstructies in chloridehoudend milieu worden ontworpen op levensduur. De vereiste prestatie van het beton kan proefondervindelijk worden bepaald. Op basis van eerdere ervaringen is de methode DuraCrete zodanig aangepast dat een levensduurontwerp nu kan worden gemaakt op drie niveaus: met behulp van ontwerptabellen, semi...

In the present research a test procedure was set up to reproduce self-healing on lime-based (both pure calcium and magnesium-calcium) mortar specimens in laboratory. After few months testing, during which the specimens were subjected to wet-dry cycles, thin sections of the specimens were prepared and observed by Polarization and Fluorescence...

It is well known that the healing rates of asphalt courses increase with the temperature. A new method, induction heating, is used in this paper to increase the lifetime of asphalt concrete pavements. Mastic will be first made electrically conductive by the addition of conductive fibers. Then it will be heated via induction energy. This will...

Bio-inhibition of buildings and structures is an important issue. In many cases building materials have biocides added to prevent growth of micro-organisms. Growth of microorganisms on building materials has several negative effects; (1) Aesthetic damage, e.g. fungi, algae grow on the material, resulting in early replacement and high cleaning...

Lime mortars have, up to a certain extent, a self-healing capacity which may contribute to their durability. Self-healing in lime mortars consists of a process of dissolution, transport and re-precipitation of calcium compounds to heal cracks and fissures. The spontaneous occurrence of self-healing in lime-based mortars is a well known...

The strength of concrete is linked to the amount of cement used. In many applications, concrete has a considerably higher strength than designed and structurally required. Lowering cement contents, thus reducing strength, significantly reduces the ecological impact of any concrete in terms of raw materials use and CO 2 output. A lower cement...

Salt crystallization is a common cause of damage to porous building materials. Recent research has shown that some chemical compounds may inhibit salt crystallization or alter the mode of crystallization, thus limiting salt damage development, provided that the inhibitor was introduced prior to salt crystallization. In this paper, a pilot study...

We have investigated whether a plaster which has two plaster layers with different pore sizes can act as a salt accumulating plaster system, in which salt crystallizes in the base layer of the plaster and not in the substrate or at the external surface. We used two substrates; fired-clay brick and Bentheim sandstone. On the substrate we applied...
