Monitoring alkali-silica reaction in structures

Evaluation of the Institution of Structural Engineers' procedure on concrete structures with alkali-silica reaction in the Netherlands

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...

Life cycle cost analysis of cathodic protection of concrete. A case study

As a case study, the cost of applying cathodic protection (CP) to the columns and beams supporting two bridges was compared to the cost of replacement (due to reinforcement corrosion). All costs during the service life of the CP system were considered: initial cost, annual checks, maintenance of anode systems and specialist supervision. It was...

Kathodisch beschermen of gedeeltelijk vervangen. Kostenvergelijking kathodische bescherming versus gedeeltelijke vervanging voor twee viaducten: Een case study

Kathodische bescherming (KB) van gewapend beton tegen schade door corrosie van de wapening is in Nederland inmiddels een geaccepteerde methode. In Cement zijn diverse artikelen verschenen over de technische kanten van KB. De economische aspecten heb-ben minder aandacht gekregen. Daarom hebben de Bouwdienst Rijkswaterstaat en TNO Bouw een case...
