Steeds vaker wordt geëist dat betonconstructies zodanig worden ontworpen dat ze een gegarandeerde levensduur hebben. Het komt voor dat een levensduur van 100 of zelfs 200 jaar wordt geëist. Maar hoe ontwerp je een constructie met voldoende levensduur? Hoe bewijs de dan dat je aan die levensduureis voldoet? En waar moet je allemaal op letten als...

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...

After the introduction of reinforced concrete it was believed that the material was extremely durable. Soon it was found however, that reinforced concrete could have serious durability problems and that special care should be taken to avoid them. Durability became an issue.

Design for durability is gradually changing from a deem-to-satisfy approach to a performance based approach. The conventional building codes give in principle only construction rules. If these rules are fulfilled, it is assumed that the structure will have an adequate durability. But specifications concerning dura-bility in codes are still on an...

Vele jaren lang is erop vertrouwd dat er een ondubbelzinnige relatie bestaat tussen de druksterkte en de treksterkte van beton. Dat vertrouwen is zelfs zo groot, dat in de betonvoorschriften de waarde van de treksterkte rechtstreeks wordt afgeleid uit die van de betondruksterkte. De verbazing was dan ook erg groot, toen bij onderzoek aan door...

Bij het ontwerpen van gewapend betonnen boortunnels wordt in Nederland sinds kort een nieuwe methode toegepast om te zorgen dat de tunnels voldoende duurzaam zijn. Het was gebruikelijk om voor betonconstructies een aantal uitvoeringseisen te stellen, bijvoorbeeld ten aanzien van de grootte van de betondekking, de water-cementfactor en de...

The service life of a building or structure is determined by the design and construction in combination with the ageing and the maintenance during use. To get grip on this combination it has advantage to present the functioning of the building or the structure on a performance level. As ageing will influence the performance, the combined effect...

In 1992, the first structure with deleterious ASR was diagnosed in the Netherlands, followed by the publication of the first Dutch guideline on the prevention of ASR in 1994. Since, ASR has been demonstrated in 40 to 50 structures over the country. Development of ASR in a series of structures on a major Dutch motorway, built in the late sixties ...

During an extensive investigation of some 25 concrete bridges and other structures suffering from alkali-silica reaction it has been found that the uniaxial tensile strength of the concrete was extremely low in relation to both the compressive strength and the splitting tensile strength. It is known that concrete with damage due to ASR has...

In de huidige generatie van betonvoorschriften wordt de duurzaamheid van betonconstructies geregeld door enerzijds eisen te stellen aan de samenstelling van de bestanddelen van beton, zoals cement, zand, grind en water. Anderzijds worden uitvoeringseisen gesteld, zoals een minimum betondekking, een maximum water/cementfactor. Duurzaamheid is...

In the past years much efforts have been spent on a new design approach for the durability of existing and new concrete structures. The results of these efforts can be seen in recent work of several international scientific committees of Rilem, CEB, CIB and FIER These have finally resulted in the Brite/Euram project DuraCrete where a design...

More than forty years ago in 1957, the first publication was published in The Netherlands indicating the possibility of damage due to ASR in a concrete structure. About ten years ago however the first concrete structure in the Netherlands with alkali-silica reaction (ASR) was documented. During the years before it was generally believed that...

Recent inspections of 20 bridges in a highway in The Netherlands revealed that ASR had affected the concrete. Until then alkali-silica reaction (ASR) was a rather rare phenomenon. In view of the expected, future importance of the maintenance of Dutch infrastructure, it was decided to start a long-term monitoring program on the decks of two of...
