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...

Cathodic protection has proven to be a reliable and economic method to stop corrosion in reinforced concrete structures. Many systems with activated titanium mesh anode embedded in cementitious mortar have functioned for more than 10 years. The service life depends on the anode/overlay system, which may be determined mainly by acid production...

Most of the Netherlands a Quaternary delta, local supplies of natural stone suitable for building are rare. These include: Quaternary bog iron ores used in early medieval times (until c. 1200); erratics, deposited in boulder clay during the Saalian ice age in the northern Netherlands and gravel from the river Meuse; Miocene lithified siliceous...

The Netherlands, with only scarce occurrences of outcropping or shallow buried natural stone, has over centuries imported huge quantities of Early Cretaceous Bentheim Sandstone and Obernkirchen Sandstone from Germany. The present paper provides an overview of their distribution and properties relevant to their use as building stone, and their...

De Oude Kerk in Delft (fig. 112) gaat terug tot 1246 en was oorspronkelijk gebouwd in vulkanisch tufsteen uit de Eifel. Later zijn twee zijbeuken en koor toegevoegd. De westelijke toren werd gebouwd tussen 1325 en 1350. In de l4 eeuw werden de zijbeuken verhoogd tot dezelfde hoogte als het schip, dat zelf in de eerste helft van de 15’ eeuw...

An overview is given of experience of alkali-silica reaction, ASR, in the Netherlands, reflecting on concrete mixes and aggregates involved, and the assessment of ASR affected structures. Recently published guidelines to prevent concrete damage due to ASR are introduced. These rely on limiting the effective amount of alkali available for...

Cement based mortars are widely used as adhesive for tiles in building and construction. They have a limited timespan during which a tile can be placed effectively in order to develop sufficient bond strength. This timespan, usually called ’open time’, is controlled, amongst others, by adding water soluble polymers such as methyl cellulose or...

Commercial, ready mix stone repair mortars have often been applied in conservation practice for the restoration of natura! stone, brick and terracotta, over the last decades with varying success in terms of durability of the repair mortar itself and compatibility with the substrate. In this research, four commercial stone repair mortars,...

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 conservation strategies would have been necessary. The application of repair techniques poses two threats towards the historic concrete: using...

A microscopic survey of over 1000 of samples of concrete and masonry mortars from structures in the Netherlands shows that, in practice, self healing occurs in historic lime and lime – puzzolana mortars, in contrast to modern cement bound concretes and mortars. Self healing may be effected by the formation of either new Ca-carbonate, CaCO3, or...

Het instandhouden van monumenten, historische binnensteden en cultuurlandschap dient een groot maatschappelijk belang: de leefbaarheid van steden, maar ook zaken als sociale veiligheid en culturele identiteit worden er in grote mate door bepaald. Welzijn en welbevinden van mensen in stedelijke gebieden worden er door vergroot. De belangrijke...

De Noordersluis bij IJmuiden is één van de grote infrastructurele werken in vooroorlogs Nederland, uitgevoerd in beton (Fig. 1). De bouw van de nieuwe sluis was onderdeel van een reeks verbeteringen aan het Noordzeekanaal: In 1909 was een staatscommissie ingesteld '(om)dat opnieuw de vraag rees of de belangen van Nederland in het algemeen en van...
